NTPTIME(8)
NAME
ntptime - read kernel time variables
SYNOPSIS
ntptime [ -chr ] [ -e est_error ] [ -f frequency ] [ -m max_error ] [ -o offset ] [ -s status ] [ -t time_constant ]
DESCRIPTION
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.
OPTIONS
-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.
