Okay, I'm experienced which is a politically correct way of saying 'old'. I remember putting a:>time and a:>date in my computer's DOS 2.1 autoexe.bat file. I guess that meant the PC XT-clone didn't even have a back up CMOS battery.For years however, I've depended on a little watch-like battery helping to keep the time as well as BIOS configuration settings. Actually, for quite a few years my computer has run continuously around the clock.
Why my computer has suddenly stopped keeping the correct time is beyond me. I first assumed it was the battery, so I replaced it with a new $5 Eveready. Hum, that didn't work.
I then looked on the Internet. What about run cmd and the w32tm /register function?
