From what I can tell, all the NT based Windows programs, which includes Win2K, are designed to automatically sync with your network server, although it gets rather complex using the built-ins to choose which server is your timesource. The expectation is that you'll have a "primary time standard" server on your network that will use the same features to sync with one of the international time servers, and pass the sync on to others on your WAN/LAN. The timing is done via the SNTP (I think that's Simple Network Timing Protocol?) setup.

Timeserve appears to be a standard network function, so it shouldn't be specific to, or limited to, Windows.

Microsoft has an article (ID 216734) that describes how to set up a Win2K master timeserver, but I'm afraid it doesn't help me much with how to set up an individual machine.

The time.windows.com site is considered a "second-level time standard site" and there are quite a number of first-level sites you can choose from, although sync to a first-level standard isn't recommended for individual users unless you have a real need for it. Many of the first-level sites have restricted access.

Microsoft article ID 262680 gives you a list of all(?) the available primary and secondary time standard sites, should you need to pick one. It's a pretty long list.
