You need to build in some sort of tolerence. But I would recommend requiring
them be connected to the net at some point. There really is no 100% way to
validate that the program has expired. Possibly you can use some sort of
encryption, and store it in the registry, or some other physical location.
The reason I like the NTP server is that the time can never be wrong, and
people should always be connected to the net anyways. Without the net, how
can you survive?
