Clocks and calendars |
Since this thread on measuring time passage has deteriorated into a
discussion of relativity; it's time to rethread:
Clocks and pendulums measure _periods_ of time: Calendars, and diaries
measure the _passage_ of time.

Nothing measures time, but the passage
of time is indicated using arbitary
units applied to a start and stop event.

That's right. Different devices for different user features.
Clocks with repeating representations give a greater dynamic range --
with one device you can easily tell the difference between any of the
86,400 seconds in a day, but aren't good for logging one-time events.
Calendars and diaries are good for storing information pertaining to
unique events but have got crappy resolution.
