Unfortunately, the POSIX.1 TZ string takes + a form that is hard to describe and is error-prone in practice. + Also, POSIX.1 TZ strings can't deal with other (for example, Israeli) + daylight saving time rules, or situations where more than two + time zone abbreviations are used in an area. + + The POSIX.1 TZ string takes the following form: + + stdoffset[dst[offset],date[/time],date[/time]] + + where: + + std and dst + are 3 or more characters specifying the standard + and daylight saving time (DST) zone names. + offset + is of the form `[-]hh:[mm[:ss]]' and specifies the + offset west of UTC. The default DST offset is one hour + ahead of standard time. + date[/time],date[/time] + specifies the beginning and end of DST. If this is absent, + the system supplies its own rules for DST, and these can + differ from year to year; typically US DST rules are used. + time + takes the form `hh:[mm[:ss]]' and defaults to 02:00. + date + takes one of the following forms: + Jn (1<=n<=365) + origin-1 day number not counting February 29 + n (0<=n<=365) + origin-0 day number counting February 29 if present + Mm.n.d (0[Sunday]<=d<=6[Saturday], 1<=n<=5, 1<=m<=12) + for the dth day of week n of month m of the year, + where week 1 is the first week in which day d appears, + and `5' stands for the last week in which day d appears + (which may be either the 4th or 5th week). + +* In POSIX.1, when a TZ value like "EST5EDT" is parsed, + typically the current US DST rules are used, + but this means that the US DST rules are compiled into each program + that does time conversion. This means that when US time conversion + rules change (as in the United States in 1987), all programs that + do time conversion must be recompiled to ensure proper results. + +* In POSIX.1, there's no tamper-proof way for a process to learn the + system's best idea of local wall clock. (This is important for + applications that an administrator wants used only at certain times-- + without regard to whether the user has fiddled the "TZ" environment + variable. While an administrator can "do everything in UTC" to get + around the problem, doing so is inconvenient and precludes handling + daylight saving time shifts--as might be required to limit phone + calls to off-peak hours.) + +* POSIX.1 requires that systems ignore leap seconds. + +These are the extensions that have been made to the POSIX.1 functions: + +* The "TZ" environment variable is used in generating the name of a file + from which time zone information is read (or is interpreted a la + POSIX); "TZ" is no longer constrained to be a three-letter time zone + name followed by a number of hours and an optional three-letter + daylight time zone name. The daylight saving time rules to be used + for a particular time zone are encoded in the time zone file; + the format of the file allows U.S., Australian, and other rules to be + encoded, and allows for situations where more than two time zone + abbreviations are used. + + It was recognized that allowing the "TZ" environment variable to + take on values such as "America/New_York" might cause "old" programs + (that expect "TZ" to have a certain form) to operate incorrectly; + consideration was given to using some other environment variable + (for example, "TIMEZONE") to hold the string used to generate the + time zone information file name. In the end, however, it was decided + to continue using "TZ": it is widely used for time zone purposes; + separately maintaining both "TZ" and "TIMEZONE" seemed a nuisance; + and systems where "new" forms of "TZ" might cause problems can simply + use TZ values such as "EST5EDT" which can be used both by + "new" programs (a la POSIX) and "old" programs (as zone names and + offsets). + +* To handle places where more than two time zone abbreviations are used, + the functions "localtime" and "gmtime" set tzname[tmp->tm_isdst] + (where "tmp" is the value the function returns) to the time zone + abbreviation to be used. This differs from POSIX.1, where the elements + of tzname are only changed as a result of calls to tzset. + +* Since the "TZ" environment variable can now be used to control time + conversion, the "daylight" and "timezone" variables are no longer + needed. (These variables are defined and set by "tzset"; however, their + values will not be used by "localtime.") + +* The "localtime" function has been set up to deliver correct results + for near-minimum or near-maximum time_t values. (A comment in the + source code tells how to get compatibly wrong results). + +* A function "tzsetwall" has been added to arrange for the system's + best approximation to local wall clock time to be delivered by + subsequent calls to "localtime." Source code for portable + applications that "must" run on local wall clock time should call + "tzsetwall();" if such code is moved to "old" systems that don't + provide tzsetwall, you won't be able to generate an executable program. + (These time zone functions also arrange for local wall clock time to be + used if tzset is called--directly or indirectly--and there's no "TZ" + environment variable; portable applications should not, however, rely + on this behavior since it's not the way SVR2 systems behave.) + +* These functions can account for leap seconds, thanks to Bradley White + (bww@k.cs.cmu.edu). + +Points of interest to folks with other systems: + +* This package is already part of many POSIX-compliant hosts, + including BSD, HP, Linux, Network Appliance, SCO, SGI, and Sun. + On such hosts, the primary use of this package + is to update obsolete time zone rule tables. + To do this, you may need to compile the time zone compiler + `zic' supplied with this package instead of using the system `zic', + since the format of zic's input changed slightly in late 1994, + and many vendors still do not support the new input format. + +* The UNIX Version 7 "timezone" function is not present in this package; + it's impossible to reliably map timezone's arguments (a "minutes west + of GMT" value and a "daylight saving time in effect" flag) to a + time zone abbreviation, and we refuse to guess. + Programs that in the past used the timezone function may now examine + tzname[localtime(&clock)->tm_isdst] to learn the correct time + zone abbreviation to use. Alternatively, use + localtime(&clock)->tm_zone if this has been enabled. + +* The 4.2BSD gettimeofday function is not used in this package. + This formerly let users obtain the current UTC offset and DST flag, + but this functionality was removed in later versions of BSD. + +* In SVR2, time conversion fails for near-minimum or near-maximum + time_t values when doing conversions for places that don't use UTC. + This package takes care to do these conversions correctly. + +The functions that are conditionally compiled if STD_INSPIRED is defined +should, at this point, be looked on primarily as food for thought. They are +not in any sense "standard compatible"--some are not, in fact, specified in +*any* standard. They do, however, represent responses of various authors to +standardization proposals. + +Other time conversion proposals, in particular the one developed by folks at +Hewlett Packard, offer a wider selection of functions that provide capabilities +beyond those provided here. The absence of such functions from this package +is not meant to discourage the development, standardization, or use of such +functions. Rather, their absence reflects the decision to make this package +contain valid extensions to POSIX.1, to ensure its broad +acceptability. If more powerful time conversion functions can be standardized, +so much the better. + + +----- Names of time zone rule files ----- + +The time zone rule file naming conventions attempt to strike a balance +among the following goals: + + * Uniquely identify every national region where clocks have all + agreed since 1970. This is essential for the intended use: static + clocks keeping local civil time. + + * Indicate to humans as to where that region is. This simplifes use. + + * Be robust in the presence of political changes. This reduces the + number of updates and backward-compatibility hacks. For example, + names of countries are ordinarily not used, to avoid + incompatibilities when countries change their name + (e.g. Zaire->Congo) or when locations change countries + (e.g. Hong Kong from UK colony to China). + + * Be portable to a wide variety of implementations. + This promotes use of the technology. + + * Use a consistent naming convention over the entire world. + This simplifies both use and maintenance. + +This naming convention is not intended for use by inexperienced users +to select TZ values by themselves (though they can of course examine +and reuse existing settings). Distributors should provide +documentation and/or a simple selection interface that explains the +names; see the 'tzselect' program supplied with this distribution for +one example. + +Names normally have the form AREA/LOCATION, where AREA is the name +of a continent or ocean, and LOCATION is the name of a specific +location within that region. North and South America share the same +area, `America'. Typical names are `Africa/Cairo', `America/New_York', +and `Pacific/Honolulu'. + +Here are the general rules used for choosing location names, +in decreasing order of importance: + + Use only valid POSIX file name components (i.e., the parts of + names other than `/'). Within a file name component, + use only ASCII letters, `.', `-' and `_'. Do not use + digits, as that might create an ambiguity with POSIX + TZ strings. A file name component must not exceed 14 + characters or start with `-'. E.g., prefer `Brunei' + to `Bandar_Seri_Begawan'. + Include at least one location per time zone rule set per country. + One such location is enough. Use ISO 3166 (see the file + iso3166.tab) to help decide whether something is a country. + If all the clocks in a country's region have agreed since 1970, + don't bother to include more than one location + even if subregions' clocks disagreed before 1970. + Otherwise these tables would become annoyingly large. + If a name is ambiguous, use a less ambiguous alternative; + e.g. many cities are named San Jose and Georgetown, so + prefer `Costa_Rica' to `San_Jose' and `Guyana' to `Georgetown'. + Keep locations compact. Use cities or small islands, not countries + or regions, so that any future time zone changes do not split + locations into different time zones. E.g. prefer `Paris' + to `France', since France has had multiple time zones. + Use mainstream English spelling, e.g. prefer `Rome' to `Roma', and + prefer `Athens' to the true name (which uses Greek letters). + The POSIX file name restrictions encourage this rule. + Use the most populous among locations in a country's time zone, + e.g. prefer `Shanghai' to `Beijing'. Among locations with + similar populations, pick the best-known location, + e.g. prefer `Rome' to `Milan'. + Use the singular form, e.g. prefer `Canary' to `Canaries'. + Omit common suffixes like `_Islands' and `_City', unless that + would lead to ambiguity. E.g. prefer `Cayman' to + `Cayman_Islands' and `Guatemala' to `Guatemala_City', + but prefer `Mexico_City' to `Mexico' because the country + of Mexico has several time zones. + Use `_' to represent a space. + Omit `.' from abbreviations in names, e.g. prefer `St_Helena' + to `St._Helena'. + Do not change established names if they only marginally + violate the above rules. For example, don't change + the existing name `Rome' to `Milan' merely because + Milan's population has grown to be somewhat greater + than Rome's. + If a name is changed, put its old spelling in the `backward' file. + +The file `zone.tab' lists the geographical locations used to name +time zone rule files. + +Older versions of this package used a different naming scheme, +and these older names are still supported. +See the file `backward' for most of these older names +(e.g. `US/Eastern' instead of `America/New_York'). +The other old-fashioned names still supported are +`WET', `CET', `MET', `EET' (see the file `europe'), +and `Factory' (see the file `factory'). + + +----- Time zone abbreviations ----- + +When this package is installed, it generates time zone abbreviations +like `EST' to be compatible with human tradition and POSIX.1. +Here are the general rules used for choosing time zone abbreviations, +in decreasing order of importance: + + Use abbreviations that consist of three or more ASCII letters. + Previous editions of this database also used characters like + ' ' and '?', but these characters have a special meaning to + the shell and cause commands like + set `date` + to have unexpected effects. + Previous editions of this rule required upper-case letters, + but the Congressman who introduced Chamorro Standard Time + preferred "ChST", so the rule has been relaxed. + + This rule guarantees that all abbreviations could have + been specified by a POSIX.1 TZ string. POSIX.1 + requires at least three characters for an + abbreviation. POSIX.1-1996 says that an abbreviation + cannot start with ':', and cannot contain ',', '-', + '+', NUL, or a digit. Draft 7 of POSIX 1003.1-200x + changes this rule to say that an abbreviation can + contain only '-', '+', and alphanumeric characters in + the current locale. To be portable to both sets of + rules, an abbreviation must therefore use only ASCII + letters, as these are the only letters that are + alphabetic in all locales. + + Use abbreviations that are in common use among English-speakers, + e.g. `EST' for Eastern Standard Time in North America. + We assume that applications translate them to other languages + as part of the normal localization process; for example, + a French application might translate `EST' to `HNE'. + + For zones whose times are taken from a city's longitude, use the + traditional xMT notation, e.g. `PMT' for Paris Mean Time. + The only name like this in current use is `GMT'. + + If there is no common English abbreviation, abbreviate the English + translation of the usual phrase used by native speakers. + If this is not available or is a phrase mentioning the country + (e.g. ``Cape Verde Time''), then: + + When a country has a single or principal time zone region, + append `T' to the country's ISO code, e.g. `CVT' for + Cape Verde Time. For summer time append `ST'; + for double summer time append `DST'; etc. + When a country has multiple time zones, take the first three + letters of an English place name identifying each zone + and then append `T', `ST', etc. as before; + e.g. `VLAST' for VLAdivostok Summer Time. + + Use "zzz" for locations while uninhabited. The mnemonic is that + these locations are, in some sense, asleep. + +Application writers should note that these abbreviations are ambiguous +in practice: e.g. `EST' has a different meaning in Australia than +it does in the United States. In new applications, it's often better +to use numeric UTC offsets like `-0500' instead of time zone +abbreviations like `EST'; this avoids the ambiguity. + + +----- Calendrical issues ----- + +Calendrical issues are a bit out of scope for a time zone database, +but they indicate the sort of problems that we would run into if we +extended the time zone database further into the past. An excellent +resource in this area is Nachum Dershowitz and Edward M. Reingold, + +Calendrical Calculations +, Cambridge University Press (1997). Other information and +sources are given below. They sometimes disagree. + + +France + +Gregorian calendar adopted 1582-12-20. +French Revolutionary calendar used 1793-11-24 through 1805-12-31, +and (in Paris only) 1871-05-06 through 1871-05-23. + + +Russia + +From Chris Carrier <72157.3334@CompuServe.COM> (1996-12-02): +On 1929-10-01 the Soviet Union instituted an ``Eternal Calendar'' +with 30-day months plus 5 holidays, with a 5-day week. +On 1931-12-01 it changed to a 6-day week; in 1934 it reverted to the +Gregorian calendar while retaining the 6-day week; on 1940-06-27 it +reverted to the 7-day week.

Grotefend +(Hannover: Hahnsche Buchhandlung, 1941), pp. 26-28. + + +----- Time and time zones on Mars ----- + +Some people have adjusted their work schedules to fit Mars time. +Dozens of special Mars watches were built for Jet Propulsion +Laboratory workers who kept Mars time during the Mars Exploration +Rovers mission (2004). These timepieces look like normal Seikos and +Citizens but use Mars seconds rather than terrestrial seconds. + +A Mars solar day is called a "sol" and has a mean period equal to +about 24 hours 39 minutes 35.244 seconds in terrestrial time. It is +divided into a conventional 24-hour clock, so each Mars second equals +about 1.02749125 terrestrial seconds. + +The prime meridian of Mars goes through the center of the crater +Airy-0, named in honor of the British astronomer who built the +Greenwich telescope that defines Earth's prime meridian. Mean solar +time on the Mars prime meridian is called Mars Coordinated Time (MTC). + +Each landed mission on Mars has adopted a different reference for +solar time keeping, so there is no real standard for Mars time zones. +For example, the Mars Exploration Rover project (2004) defined two +time zones "Local Solar Time A" and "Local Solar Time B" for its two +missions, each zone designed so that its time equals local true solar +time at approximately the middle of the nominal mission. Such a "time +zone" is not particularly suited for any application other than the +mission itself. + +Many calendars have been proposed for Mars, but none have achieved +wide acceptance. Astronomers often use Mars Sol Date (MSD) which is a +sequential count of Mars solar days elapsed since about 1873-12-29 +12:00 GMT. + +The tz database does not currently support Mars time, but it is +documented here in the hopes that support will be added eventually. + +Sources: + +Michael Allison and Robert Schmunk, +"Technical Notes on Mars Solar Time as Adopted by the Mars24 Sunclock" + (2004-03-15). + +Jia-Rui Chong, "Workdays Fit for a Martian", Los Angeles Times +(2004-01-14), pp A1, A20-A21.

+

The tz database

+

+The public-domain time zone database contains code and data +that represent the history of local time +for many representative locations around the globe. +It is updated periodically to reflect changes made by political bodies +to UTC offsets and daylight-saving rules. +This database (often called tz or zoneinfo) +is used by several implementations, +including +the GNU C Library used in +GNU/Linux, +FreeBSD, +NetBSD, +OpenBSD, +Cygwin, +DJGPP, +HP-UX, +IRIX, +Mac OS X, +OpenVMS, +Solaris, +Tru64, and +UnixWare.

+

+Each location in the database represents a national region where all +clocks keeping local time have agreed since 1970. +Locations are identified by continent or ocean and then by the name of +the location, which is typically the largest city within the region. +For example, America/New_York +represents most of the US eastern time zone; +America/Indianapolis represents most of Indiana, which +uses eastern time without daylight saving time (DST); +America/Detroit represents most of Michigan, which uses +eastern time but with different DST rules in 1975; +and other entries represent smaller regions like Starke County, +Kentucky, which switched from central to eastern time in 1991. +To use the database, set the TZ environment variable to +the location's full name, e.g., TZ="America/New_York".

+

+In the tz database's +FTP distribution, +the code is in the file tzcodeC.tar.gz, +where C is the code's version; +similarly, the data are in tzdataD.tar.gz, +where D is the data's version. +The following shell commands download +these files to a GNU/Linux or similar host; see the downloaded +README file for what to do next.

+
wget 'ftp://elsie.nci.nih.gov/pub/tz*.tar.gz'
+gzip -dc tzcode*.tar.gz | tar -xf -
+gzip -dc tzdata*.tar.gz | tar -xf -
+
+

+The code lets you compile the tz source files into +machine-readable binary files, one for each location. It also lets +you read a tz binary file and interpret time stamps for that +location.

+

+The data are by no means authoritative. If you find errors, please +send changes to the time zone +mailing list. You can also subscribe to the +mailing list, retrieve the archive of old +messages (in gzip compressed format), or retrieve archived older versions of code +and data.

+

+The Web has several other sources for time zone and daylight saving time data. +Here are some recent links that may be of interest. +

Precision timekeeping

Time notation

+
    +
  • +A Summary of +the International Standard Date and Time Notation is a good +summary of ISO +8601:1988 - Data elements and interchange formats - Information interchange +- Representation of dates and times (which has been superseded by +ISO 8601:2000).
    • +
  • +Section 3.3 of Internet RFC 2822 +specifies the time notation used in email and HTTP headers.
    • +
  • +Internet RFC +3339 specifies an ISO 8601 profile for use in new Internet +protocols.
    • +
  • +The +Best of Dates, the Worst of Dates covers many problems encountered +by software developers when handling dates and time stamps.
    • +
  • +Alphabetic time zone abbreviations should not be used as unique +identifiers for UTC offsets as they are ambiguous in practice. For +example, "EST" denotes 5 hours behind UTC in English-speaking North +America, but it denotes 10 or 11 hours ahead of UTC in Australia; +and French-speaking North Americans prefer "HNE" to "EST". For +compatibility with POSIX the +tz database contains English abbreviations for all time +stamps but in many cases these are merely inventions of the database +maintainers.
