w32tm /ntte
Convert a NT system time, in (10^-7)s intervals from 0h 1-Jan 1601,
into a readable format.
w32tm /ntpte
Convert an NTP time, in (2^-32)s intervals from 0h 1-Jan 1900, 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>]
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
dataonly - display only the data, no graphics.
samples: - collect samples, then stop. If not
specified, samples will be collected until Ctrl-C is pressed.
packetinfo - print out NTP packet response message.
ipprotocol - specify the IP protocol to use. The default is
to use whatever is available.
w32tm /config [/computer:] [/update]
[/manualpeerlist:] [/syncfromflags:]
[/LocalClockDispersion:]
[/reliable:(YES|NO)]
[/largephaseoffset:]
computer: - adjusts the configuration of . If not
specified, the default is the local computer.
update - notifies the time service that the configuration has
changed, causing the changes to take effect.
manualpeerlist: - sets the manual peer list to ,
which is a space-delimited list of DNS and/or IP addresses.
When specifying multiple peers, this switch must be enclosed in
quotes.
syncfromflags: - sets what sources the NTP client should
sync from. should be a comma separated list of
these keywords (not case sensitive):
MANUAL - sync from peers in the manual peer list
DOMHIER - sync from an AD DC in the domain hierarchy
NO - sync from none
ALL - sync from both manual and domain peers
LocalClockDispersion: - configures the accuracy of the
internal clock that w32time will assume when it can't acquire
time from its configured sources.
reliable:(YES|NO) - set whether this machine is a reliable time source.
This setting is only meaningful on domain controllers.
YES - this machine is a reliable time service
NO - this machine is not a reliable time service
largephaseoffset: - sets the time difference between
local and network time which w32time will consider a spike.
w32tm /tz
Display the current time zone settings.
w32tm /dumpreg [/subkey:] [/computer:]
Display the values associated with a given registry key.
The default key is HKLM\System\CurrentControlSet\Services\W32Time
(the root key for the time service).
subkey: - displays the values associated with subkey
of the default key.
computer: - queries registry settings for computer .
w32tm /query [/computer:]
{/source | /configuration | /peers | /status}
[/verbose]
Display a computer's windows time service information.
computer: - query the information of . If not
specified, the default is the local computer.
source: display the time source.
configuration: display the configuration of run-time and where
the setting comes from. In verbose mode, display the undefined
or unused setting too.
peers: display a list of peers and their status.
status: display windows time service status.
verbose: set the verbose mode to display more information.
w32tm /debug {/disable | {/enable /file: /size: /entries:
[/truncate]}}
Enable or disable local computer windows time service private log.
disable: disable the private log.
enable: enable the private log.
file: - specify the absolute filename.
size: - specify the maximum size for circular logging.
entries: - contains a list of flags, specified by number and
separated by commas, that specify the types of information that
should be logged. Valid numbers are 0 to 300. A range of numbers
is valid, in addition to single numbers, such as 0-100,103,106.
Value 0-300 is for logging all information.
truncate: truncate the file if it exists.
