Usually got it right. Slightly off topic (this is a.f.c after all), I remember a site where the receptionist didn't like 24-hour time. Every day at 1 p.m., when the time display changed to 13:00, she'd change it to 1:00. When she came in the next morning, the display would be reading 21:00, so she'd change it back to 9:00. As a result, the only time that the switch would see a midnight crossing was on weekends, when the switch was unmanned. Therefore, the date in the switch (and in the call records it generated) would only advance by two days a week. > Somewhere along the line they got direct connections to > time sources. > > Many years ago WU supplied a time signal and clocks.

I remember that from my school days. I think "spring ahead" was easier because the clocks would step ahead by one minute every second, so in a minute the adjustment was complete. Going the other way was trickier - maybe they lost count. -- /~\ Charlie Gibbs | Microsoft is a dictatorship. \ / <cgibbs@kltpzyxm.invalid> | Apple is a cult.
