w32tm /ntte
Convert a NT system time, in (10^-7)s intervals from 0h 1-Jan 1601,
into a readable format.

w32tm /resync [/computer:] [/nowait] [/rediscover] [/soft]
Tell a computer that it should resynchronize its clock as soon
as possible, throwing out all accumulated error statistics.
computer: - computer that should resync. If not
specified, the local computer will resync.
nowait - do not wait for the resync to occur;
return immediately. Otherwise, wait for the resync to
complete before returning.
rediscover - redetect the network configuration and rediscover
network sources, then resynchronize.
soft - resync utilizing existing error statistics. Not useful,
provided for compatibility.
w32tm /stripchart /computer: [/period:]
[/dataonly] [/samples:] [/packetinfo] [/ipprotocol:<4|6>] [/rdtsc]
Display a strip chart of the offset between this computer and
another computer.
computer: - the computer to measure the offset against.
period: - the time between samples, in seconds. The
default is 2s

ipprotocol - specify the IP protocol to use. The default is
to use whatever is available.

The output displays TSC and FILETIME values captured before the
NTP request is sent, TSC value after an NTP response is received
along with NTP roundtrip and time offset values.
