Recently (last couple of days), my computer has been gaining time, approximately 1 minute per hour. Attempts to re-synch the time over the internet (using both the Windows internet time synch feature, and an independent app) have failed most of the time.
I recognize that a failing CMOS battery will cause the computer clock to lose time, but can it also cause the clock to gain time? The battery is old enough (several years) that failure is to be expected any time now, but are my symptoms indicative of battery failure? The computer is functioning properly in all other respects.
Any help would be welcome.
