I used to see that all the time with old 286/386 systems, and it was a
battery problem. What seemed to be happening was that, on it's own, the
battery had just enough charge to keep the memory on the RTC chip alive, but
not enough to power the oscillator in the chip that ticks the clock. When
the PC is on, the chip is powered by the PC's power supply, so it runs
normally. When you turn it off, time stands still. Replacing the battery
almost always fixed the problem.
