Description

System Administration Commands                                      ntptime(8)



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 Preci-
       sion Timekeeping". A similar display can be  obtained  using  the  ntpq
       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.
