ntptime − read kernel time variables
ntptime [ −chr ] [ −e est_error ] [ −f frequency ] [ −m max_error ] [ −o offset ] [ −s status ] [ −t time_constant ]
This program is useful only with special kernels described in the A Kernel Model for Precision Timekeeping page. It reads and displays time-related kernel variables using the ntp_gettime() system call. A similar display can be obtained using the ntpdc program and kerninfo command.
|
−c |
Display the execution time of ntptime itself. |
−e est_error
Specify estimated error, in microseconds.
−f frequency
Specify frequency offset, in parts per million.
|
−h |
Display help information. |
−m max_error
Specify max possible errors, in microseconds.
−o offset
Specify clock offset, in microseconds.
|
−r |
Display Unix and NTP times in raw format. |
−s status
Specify clock status. Better know what you are doing.
−t time_constant
Specify time constant, an integer in the range 0-10.
