I guess it's clear to everyone at this point, since there hasn't been an update in three years, but I just wanted to state in public that the development on NetTime is discontinued.
There is no strong reason for NetTime to continue to exist at this point. Windows NT, 2000 and XP now have built-in NTP support directly from Microsoft. Windows 9X and ME are ending their supported lifespan, and if you still want to use NetTime on them, it should continue to work as long as they do.
If anyone finds further use for the NetTime code, please let me know. Otherwise, thanks to all who participated, and hopefully we'll work together on some other project sometime in the future.
