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 tounderstand, 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 therange 0-10.
