Re: w32time
In a workgroup, by default, each computer independently synchronizes its
time with an Internet time source - the default is time.microsoft.com.
There should be entries in the System Event Log with Source of Time-Service
indicating whether the time synchronization was successful and with what
time source.
It's probably a good idea to use a single server as the time source for all
the other servers if you aren't doing so already; this may ameliorate your
problem. The default settings for time synchronization will usually keep
the time on all the servers within a second, so a difference of over a
minute would be quite unusual.
To configure the time service on the computer that will serve as the time
source for the others, use these commands:
w32tm /config /syncfromflags:manual /manualpeerlist:time.nrc.ca /update
w32tm /resync /rediscover
Note that I'm in Canada and choose to use time.nrc.ca as the Internet time
source (manualpeerlist in the above command). You might want to use a
different time source that is nearer to you - see for example
http://support.ntp.org/bin/view/Servers/StratumTwoTimeServers and
http://support.ntp.org/bin/view/Servers/WebHome.
You should see entries in the System Event Log indicating that the time
service has successfully synchronized after the resynch command.
On the other servers, configure them to use the one configured above (in the
commands, this computer is called TimeSource.mine.local):
w32tm /config /syncfromflags:manual
/manualpeerlist:TimeSource.mine.local /update
w32tm /resync /rediscover
The w32tm command has a number of options for monitoring and diagnosing time
synchronization issues, but I've not had a need to explore them - it usually
just works!
Use the command:
w32tm /?
to get a list of the options with desriptions. Note that different versions
of Windows Server support different options for the w32tm command. For
example, the /query option is available in Server 2008 but not Server 2003.

It is perfectly useless to know the right answer to the wrong question.
