How can I synchronize time between a Unix machine and an NT machine?

Some common protocols for doing this are:

Daytime (RFC 867)
Time (RFC 868)
SNTP (RFC 2030)

The FAQ at http://www.jguru.com/jguru/faq/view.jsp?EID=10435 tells you where you can find these RFCs.

In all three cases, you will need a server running which provides the date and time for the remote clients. Many OSes have built-in servers which you can run for this purpose.
