Yep, went through the same route until I figured out that GPS time is a bit ahead of UTC. We simply use a windows NTP server for internal use at work, and I won't recommend doing so, because it went off the rails once for a while despite of having several upstream servers pointed to.
Also there's a community out there dedicated for atomic clocks for civil use, it'd be fun to have one, set it up, and watch it ticking.

I thought about going the GPS route with it but didn’t want to mess with it. -Andy
