I... Actually don't know.

The real time clock continues to move in real time under reasonable conditions. If it's in a weird year it's either because you've decided to run a disk you found in a cave, left by the Ancient Ones, or you're cheating at Animal Crossing.

I'm a little unclear on how the rest of the clocks typically work together. If your program is drawing from one that gets stopped for a while, I guess yeah, a minute could totally be weeks long, and I'm in the picture as a falsehood believer.
