 .Dt TIME 3

 .Sh NAME
 .Nm time
 .Nd get time of day
 .Sh LIBRARY
 .Lb libc
 .Sh SYNOPSIS
 .In time.h
 .Ft time_t
 .Fn time "time_t *tloc"
 .Sh DESCRIPTION
 The
 .Fn time
 function
 returns the value of time in seconds since 0 hours, 0 minutes,
-0 seconds, January 1, 1970, Coordinated Universal Time.
+0 seconds, January 1, 1970, Coordinated Universal Time (UTC).
 If an error occurs,
 .Fn time
 returns the value
 .Po Vt time_t Pc Ns \-1 .
 .Pp
 The return value is also stored in
 .No \&* Ns Va tloc ,
 provided that
 .Va tloc
 is non-null.
 .Sh ERRORS
 The
 .Fn time
 function may fail for any of the reasons described in
 .Xr clock_gettime 2 .
 .Sh SEE ALSO
 .Xr clock_gettime 2 ,
 .Xr gettimeofday 2 ,
 .Xr ctime 3
 .Sh STANDARDS
 The
 .Nm
 function conforms to
-.St -p1003.1-2001 .
+.St -p1003.1-2008 .
 .Sh HISTORY
-A
+The
+.Fn time
+system call first appeared in
+.At v1 .
+Through the
+.At v3 ,
+it returned 60 Hz ticks since an epoch that changed occasionally, because it
+was a 32-bit value that overflowed in a little over 2 years.
+.Pp
+In
+.At v4
+the granularity of the return value was reduced to whole seconds,
+delaying the aforementioned overflow until 2038.
+.Pp
+.At v7
+introduced the
+.Fn ftime
+system call, which returned time at a millisecond level,
+though retained the
+.Fn gtime
+system call (exposed as
+.Fn time
+in userland).
+.Fn time
+could have been implemented as a wrapper around
+.Fn ftime ,
+but that wasn't done.
+.Pp
+.Bx 4.1c
+implemented a higher-precision time function
+.Fn gettimeofday
+to replace
+.Fn ftime
+and reimplemented
+.Fn time
+in terms of that.
+.Pp
+Since
+.Fx 9
+the implementation of
 .Fn time
-function appeared in
-.At v6 .
+uses
+.Fn clock_gettime "CLOCK_SECOND"
+instead of
+.Fn gettimeofday
+for performance reasons.
 .Sh BUGS
 Neither
 .St -isoC-99
 nor
 .St -p1003.1-2001
 requires
 .Fn time
 to set
 .Va errno
 on failure; thus, it is impossible for an application to distinguish
 the valid time value \-1 (representing the last UTC second of 1969)
 from the error return value.
 .Pp
-Systems conforming to earlier versions of the C and
-.Tn POSIX
+Systems conforming to earlier versions of the C and POSIX
 standards (including older versions of
 .Fx )
 did not set
 .No \&* Ns Va tloc
 in the error case.
