A point in time, conceptualized as the amount of time that has elapsed from some arbitrary zero-point, called an epoch. a timestamp may be expressed with vary degrees of precision, e.g. YYYY, YYYYMMDD, YYYMMDDhhmmss, etc.
Examples: 1982, 1997-07, 2001-09-10, 2006-02-19 15:25:30
Applicable constraints:
1. precsion - required precision of timestamp, expressed as a substring of YYYYMMDDhhmmss.sss
Note: not to be confused with an arbitrary measurement of time (e.g. 3 days 2 hours 15 mins), which should be represented using a PhysicalQuantity with the appropriate unit of time.
