Helping my daughter today with a "new" (refurbed actually) ASUS laptop T4500, with a Home Premium 64-bit OS on it.
Everything more or less worked okay out of the box as far as I can tell.
But in the initial setup (the stuff that launches the first time you turn the computer on), when I (correctly) picked my time zone - eastern US - the clock set one hour behind. Daylight time was correctly detected; without it I'd have been two hours behind.
I spent a little time trying to figure that out, couldn't get it to take, and finally copped out and picked Atlantic time, one time zone to the east of where I really am.
So now the time displays correctly, but I'm pretty bugged that, after setting up maybe a dozen computers from Windows 98 to Windows 7, I am faced with a stupid glitch like this that I've never seen before.
Other than the date/time control panel, which I've of course tried and failed with, is there some odd hidden setting that would explain why I have to have the computer set to the Atlantic daylight time zone to correctly display the eastern daylight time?
