OPERATIONAL DEFINITION OF TIME

According to Albert Einstein, time is what clocks measure. But time is an indirect measure because the duration of something does not affect directly the clock. The clock only indicates the position of the Sun relative to a point on the Earth. It looks like more a space measurement that temporary.

Reference Proposition: We see the becoming, we intuit the duration and time is intelligible. The duration is the increased existence of something.

Operationally time is defined as: "t is (d), i" that is read: time is the measure of the duration since a start time set.

Process:
1- The clock shows 10:37 AM.
2- We look the time in the clock.
3- We intuit the 10 hours since midnight.
4- We intuit the 37 minutes since 10:00 AM.
5- We think the time 10:37 AM.

Without step 3 and 4 we only see that the hands go over the graduated dial of the clock.
