I believe the date system you are refering to is the Scaliger system which is based off of Nov 24 -4713 (Gregorian). This measures time in terms of Julian days (not to be confused with the Julian calendar which is completely different :-)) and, as a piece of trivia, is how DB2/400 Date datatype dates are currently physically stored on auxiliary storage. Using a 4-byte integer representation, this gives a date range of 11.7 million years (and some people are worried about 2000 and 9999...). Lilian (named after the astronomer Aloysius Lilius (or Lilio) who advised Pope Gregory XIII back in the 16th century) is based off of Oct 15 1582 (Gregorian), and is the basis for the ILE CEE Date APIs found in the System API Reference.
