w32tm [ -tz | -s [computer] | -adj | -adjoff | -source | -once ]
      [-test] [-v] [-p <port>] [-period <freq>]

    Primary options:
    -tz       print the local time zone info and exit.
    -s [<computer>] force the given computer (or the local computer if
              none is given) to resynchronize, then exit.
    -adj      set the computer's system clock frequency to the last
              frequency determined during synchronization, then exit.
    -adjoff   set the computer's system clock frequency the system
              default, then exit
    -source   choose a synchronization source, then exit. Note that a
              source is chosen before each synchronization, so this is
              useful only in showing that a source could be found.
              Remember to use -v to see the output.
    -once     do only one synchronization, then exit.
    Otherwise, run continuously as a client, synchronizing the local
              clock until ctrl-c is pressed.

    The program will also run as a server any time the service
    would (when it is on a DC, or when the registry flag is set).

    The following options can be used in conjunction with the above:
    -test     prevent the time on the local system from actually
              being modified.
    -v        print out a verbose description of what the program is
              doing. This is usually needed since otherwise the
              program produces no output. The exceptions are -s and -tz.
    -p <port> set the server port.
    -period <freq> set the sync period just as in the registry. That is:
              0 == once a day
              65535 == once every 2 days
              65534 == once every 3 days
              65533 == once every week (7 days)
              65532 == once every 45 min until we get 3 good syncs, then
                           once every 8 hrs (3/day)
              65531 == once every 45 min until we get 1 good sync, then
                           once every day
              Otherwise, <freq> times per day.
