There was a good one about NTP and microsecond precision that had programming but was more a discussion of how hard time is to get right at great precision.
I had a similar experience after purchasing a license. Admittedly a few years back now, but I seemed to encounter issues that would strike at the most inopportune time. I eventually moved to an RDP based setup and haven't looked back.
FYI-- I have many of the same complaints and found that the browser extension https://www.fbpurity.com/ is able to clean up a lot of the cruft as well as put the timeline back in chronological order.
