TIMESYNC(8)                                           TIMESYNC(8)

          timesync - synchronize the system clock to a time source

          aux/timesync [ -a accuracy ] [ -S stratum ] [ -s netroot ] [
          -frnDdLilG ] [ timeserver ]

          Aux/timesync synchronizes the system clock to a time source,
          by default a file server.  The options are:

          -f  synchronize to a file server.  If timeserver is missing,
              use /srv/boot.

          -r  synchronize to the local real time clock, #r/rtc.

          -L  used with -r to indicate the real time clock is in local
              time rather than GMT.  This is useful on PCs that also
              run the Windows OS.

          -n  synchronize to an NTP server.  If timeserver is missing,
              dial the server udp!$ntp!ntp.

          -D  print debugging to standard error

          -d  put file containing last determined clock frequency in
              directory dir, default /tmp.

          -i  stands for impotent.  Timesync announces what it would
              do but doesn't do it.  This is useful for tracking
              alternate time sources.

          -a  specifies the accuracy in nanoseconds to which the clock
              should be synchronized.  This determines how often the
              reference clock is accessed.

          -G  causes timesync to use a gps server (see gpsfs(8)) as a
              time source.

          -s  causes timesync to listen for UDP NTP requests on the
              network rooted at netroot. Up to 4 -s options are

          -S  sets the stratum number to stratum.

          -l  turns on logging to /sys/log/timesync.

          /tmp/ts.<sysname>.<type>.timeserver  where the last
