System Time synchronization

[arcvonz]

We have a time critical smart client application running on Windows 2000/XP
systems.
Is there any reliable service that would help in syncing the local system
time to atomic clock or local time at the least in case the user changes the
system clock in purpose or inadvertently?

- Network synchronization solutions in the network is manual I believe?
- Web service based sync could work but will not if the user is off line.

Any other viable solutions?

Thanks much,
Arc

WinXP includes auto-sync of machine time. I don't know about W2000.

It is a machine-wide setting. You can specify the interval and the list of
NTP servers to connect to.
It will not work if the user is not connected to the net.

You may want to implement the RFC and connect to a time server:
