'In relativity, proper time is time measured by a single clock between

I'm talking about the clocks being meaningless.

If the two observers start an event at the same moment and end the
event at the same moment, then the same amount of time has passed for
both observers, regardless of what their clocks say.

   And how do YOU determine that the "same amount of time has passed"?

Because they started their clocks simultaneously and stopped their
clocks simultaneously.

All that matters is the length of time between two moments.

And since their start event was simultaneous and their end event was
simultaneous, the length of time is the same for both observers.
