I've never paid attention, just assumed that after the clock hit 2:59:59, the next tick would be 2:00:00, but that's not the way it happened.
My clock stopped at 1:59:59, and left me without a visible working clock for an hour, but curiously, a test folder created at
2:40 showed an
incorrect creation time of
1:40, i.e., the clock had already been set back an hour behind the scenes.
I can't begin to figure out the logic involved here, but it seems to me that macOS's generating an incorrect creation time is a bug regardless of the logic. (Reported)
