Proposed Basic model:

Hierarchy of generality and complexity:

Regime 0: Events, Allen operators – archaeological layers, sediments and ice core layers, geological. ISO7601 bad idea

Regime 1: Physical regular event defines a clock, timescales, precision integer arithmetic ordinals ‘intervals’, no time <0, TAI. ISO8601 bad idea

Regime 2: Temporal CRS with Epoch (datum), direction, tick marks/precision, normal real arithmetic, real number line, to interpolate below precision, extrapolate before 0

Regime 3: Calendars, durations, complex calculations including the very simple Years BCE/CE. UT1 (UT0? UT2?)

Regime 4: astronomical? local solar, sidereal time,
