SPTP — Chap. 5, p. 91

The grammar for expressing time values, and especially dates, is very much Western
time oriented. It may appear as regressive compared to time internationalization
found in modern programming languages like Java, or even C! Although what is pre-sented
here is certainly sufficient for most real time applications, it cannot serve as a
general notion of time, usable by all sorts of UML models throughout many types of
application domains.
By the way, there was not a year 0, there will be hopefully a year 10000, and there
were negative years!

Valid comment but definitely outside the scope of the RTF, closed no change
