ntptime(1) -- Linux man page

 

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 theA Kernel Model for Precision Timekeepingpage. 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.
