My main g4 mini seems to be struggling with keeping time and has been for ages. After a reboot it keeps time just fine for days (with ntpd running). Then at some point it just falls apart and starts losing time steadily (like, a few minutes a day). This time round I kept an eye on it, to see when it's gonna start doing that and it took about 20 days. Nothing interesting in the logs. When restarted, ntpd complains: Dec 25 12:06:29 snips ntpd[18464]: kernel reports TIME_ERROR: 0x6041: Clock Unsynchronized Anything I can do to debug (and hopefully fix) this? The behavior is reproducible, but as you can see it takes weeks for it to manifest. Some 32-bit counter overflows?
