Last move with zero time on the clock?

I wonder how it's possible to have made a move if I don't have time available. It is an inconsistency. If I could make a movement I should have time available on the clock, if I don't have time on the clock I should not have been able to make the movement. But never being able to make a move and have zero time.

Yes, it's not possible. When flag drops, you lose the game.

You must have 0.01 second minimally on the clock, otherwise you timeout.
Please see this game.

In chess.com I won a game with 0.0 second but I am pretty sure that there is hidden two decimal in clock that their GUI didnt display ( e.g 0.05 sec) but rounded to one decimal.

If you overstep the time limit you lose, pretty sure.

The problem as I see it: different interfaces (App, OS) show different (rounded, truncated) numbers. Some show 0s, some 0.1s, some 0.03s. For me it is not entirely clear. Some games end 0.0s vs. 0.0s - what's the verdict? Btw, lag (compensation) is an issue as well.

PS: look at this game, what has happened finally? At least, I was somewhat lucky. ;) :D

Yes, I understand, it is a problem of tenths of a second (exposed on the clock) against hundredths of a second (hidden). Thanks
