I have a G4 AGP (1GHz) running OSX 10.4.8 that did not get the word on the change to Daylight Savings time. It was one hour behind all of the house clocks, including the atomic clock that reset itself. I don't know if the problem is with Mac OSX or the Apple Americas/U.S. (time.apple.co) network clock. If I check the "Set date & time automatically" option in the Date & Time System Prefs the time goes back one hour. The only way I can get the correct time to display is to uncheck the option. Anyone else having problems? Dick
