In grad school I ended up managing a small cluster of SGI machines in our department. After setting up two new machines the time was wrong. I fixed it. Hours later it’s off by 12 minutes. Back and forth I go for a week thinking SGI has crappy clocks.
Found out SGI machines seek out each other and elect a TimeMaster based on up-time, clock changes. Turns out we had a machine that predated all of the new ones that had not been restarted in 2 years that had incorrect time.

Definitely workhorse machines.
