W32tm
Updated: January 21, 2005
A tool used to diagnose problems occuring with Windows Time.
Syntax
{/config [/computer:ComputerName] [ [/update]
[/manualpeerlist:ListOfComputerNames] ] [/syncfromflags:ListOfFlags]
] | /monitor | /ntte | /ntpte |
/register|/resync [{:ComputerName] [/nowait]
| [/rediscover}] | /tz | /unregister}
Parameters
/config[ /computer:ComputerName]
[ [ /update] [ /manualpeerlist:ListOfComputerNames]
] [ /syncfromflags:ListOfFlags]
Adjusts the time settings on the local or target
computer. Time synchronization peers can be set with
the /manualpeerlist switch. Changes to
configuration are not used by Windows Time unless
the service is restarted or the /update
switch is used. /syncfromflags can be used to
set the types of sources used for synchronization,
and can be set to either MANUAL to use the
manual peer list or DOMHIER to synchronize
from a domain controller.
/monitor
Monitors the target computer or list of computers.
/ntte
Converts an NT system time into a readable format.
/ntpte
Converts an NTP time into a readable format.
/register
Register to run as a service and add default
configuration to the registry.
/resync[{ :ComputerName] [ /nowait]
| [ /rediscover}]
Resynchronize the clock as soon as possible,
disregarding all accumulated error statistics. If no
computer is specified, the local computer will
resynchronize. The command will wait for
resynchronization unless the /nowait switch
is used. Currently used time resources will be used
unless /rediscover is used, which will force
redetection of network resourced before
resynchronization.
/ tz
Display the current time zone settings.
/ unregister
Unregister service and remove all configuration
information from the registry.
/?
Displays help at the command prompt.
Caution
- Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.
Remarks
- This tool is designed for network administrators to use for
diagnosing problems with Windows Time.
For more information, see net time in Related Topics.
- For the Windows Time service to use the changed made with W32tm, it must be notified of the changes. To notify Windows Time, at the command prompt, type w32tm /config /update.
Examples
To display the current time zone settings, type:
w32tm /tz
