NAME
ntptime - Display Kernel Time Variables.
SYNOPSIS
/usr/sbin/ntptime [-chr] [-e est_error] [-f frequency]
[-m max_error] [-o offset] [-s status] [-t time_constant]
DESCRIPTION
This program is used to display or set the kernel variables
used by NTP as described in the documentation at
file:///usr/share/doc/ntp/kern.html entitled "A Kernel Model
for Precision Timekeeping". A similar display can be
obtained using the ntpdc program and kerninfo command. The
actual meaning of these variables is rather difficult to
understand, but the ntptime program is primarily useful to
determine if the variables are set at all or to clear them
if they are.
OPTIONS
-c Display the time taken to call ntp_gettime (us)
-e esterror
Set the estimated error, in microseconds.
-f frequency
Set the frequency error (-500 .. 500), in parts per
million.
-h Display help information.
-m maxerror
Set the maximum possible error, in microseconds.
-o offset
Set the offset in microseconds.
-r Print the unix and NTP time raw
-s status
Set the status bits. Do not use this unless you know
what you are doing.
-t timeconstant
Set the log2 of PLL time constant, an integer in the
range 0-10.
