Your PC also has a quartz oscillator and battery backing, there's no way it synchronizes time from AC power.

- wiz21c 9y agosure, I just meant my PC has a very sophisticated (hence fragile) way of keeping its time accurate. And forget about battery backing, it's a desktop and its bios battery is long dead :-) (hence the atomic clock)
- Piskvorrr 9y agoOnce you do synchronize it off the net, it's still the quartz oscillator keeping the local beat, as it were :)
- isostatic 9y agoI synchronize with ntp every 500 million cpu cycles :p
- c3833174 9y agoIIRC modern operatings systems use counters in the CPU for timekeeping instead of directly accessing the RTC
- Piskvorrr 9y agoWell, the CPU is somewhat beyond my ken. You are right, of course - yet I think there would be another oscillator driving the clock generator as well. Turtles all the way down ;)
