LENGTH AND TIME INTERVALS

Previous note:

These are reflections on space and time to come to interesting conclusions.
Both length and time are made up of intervals. An interval is the distance or separation between two points in space (length) or between two sequential moments in becoming (time).
Length is measured in all three directions of space. Time (1) is the separation between two sequential moments in becoming, one of which is the beginning and the other the end. Between the beginning and the end there are sequential changes. Time is measured in only one direction, from the past to the future. These are mathematical definitions because they describe physical magnitudes or quantities. Time intervals are periodic and for this reason are known (subperceptibly) to the observer.

The idea that time flows is not a metaphor, it is a reality. Time flows (passes) second by second, minute by minute.

n conclusion:
Time (2) is the periodic becoming that we use to measure the duration of things. Date is the length of the year. The time is the length of the day. Age is the length of a person's life. Time is made up of natural (day and year) and artificial (clocks) periodic intervals.
Note:
(1) and (2) are definitions of time from two different approaches.
