It reads and displays time-related kernel variables using the -.Xr ntp_gettime 2 +.Fn gettime and -.Xr ntp_adjtime 2 +.Xr adjtime 2 system calls if available. A similar display can be obtained using the .Xr ntpdc 8 program's .Ic kerninfo command. +.Pp The following options are available: .Bl -tag -width indent .It Fl c Display the execution time of .Nm itself. .It Fl e Ar est_error Specify estimated error, in microseconds. .It Fl f Ar frequency Specify frequency offset, in parts per million. .It Fl h -Display times in Unix timeval format. -Default is NTP format. +Display help information. .It Fl l Specify the leap bits as a code from 0 to 3. .It Fl m Ar max_error -Display help information. +Specify max possible errors, in microseconds. .It Fl o Ar offset Specify clock offset, in microseconds. .It Fl r Display Unix and NTP times in raw format. .It Fl s Ar status .It Fl t Ar time_constant Specify time constant, an integer in the range 0-4. .El .Sh SEE ALSO -.Xr ntp_adjtime 2 , -.Xr ntp_gettime 2 , +.Xr adjtime 2 , .Xr ntpdc 8
