DO NOT have the "halt at end" option turned on. Even worse would be to have the clock beep when time has expired - a fallen flag is up to the players to notice (at least here in the US).

I have seen this situation play out before - the TDs here frequently tell the players to have those options disabled.

I too have a Chronos and if I knew how to disable the "move counter" I would - even though I do know the scoresheet and not the clock are responsible for tracking moves, especially with time controls with 2 or more time controls.

Which is true, but that's poor design. The count of the number of presses should be part of the display. That way the players can ensue that it's synchronised with the scoresheet.

On the DGT clock, whether the clock stops on detection of a flag fall varies with the option selected. Unless hacked by an arbiter, it's usual behaviour for them to stop on the final control with increment.

No clock can possibly know when the "end" has been reached.

The reason is that clocks have no MOVE counter.

Clocks do have a BUTTON PRESS counter, but its correlation with the count of moves is imperfect.
Clocks cannot know whether a player forgot to press his clock, or whether confusion caused extra presses.
