Yes.

The fed wants the official to keep the count, not rely on any clocks.

what is wrong with relying on a clock in some situations? the fed seems to be going a bit overboard there. They can just tell me not rely on the clock and that is great but there can still be exceptions, like this one

I just cannot imagine trying to explain to a coach how I am not supposed to fix my mistake even though everyone in the gym can see that I screwed up;
