Yeah, until you sync to ~1ms with 99.999% accuracy required for production-specific services, you don't really realize how big of a pain in the ass this particular problem is. And syncing to ~1ms is comparably easy, although annoying as hell. The problem the OP company is trying to solve is quite a bit tougher. Of course it sounds extremely stupid, which is why there are so many drive-by "NTP solved this already" comments from people who don't deal with millisecond precision at high accuracy requirements, god forbid sub-millisecond.
