What business > reason is there for dealing with such early dates? Astronomers even today use the "Julian day" count to avoid confusion with changing calendars. The Julian day count is the number of days since noon (GMT) on January 1, -4712, i.e., January 1, 4713 BC. This scheme was proposed by Julius J. Scaliger in 1583 (so has nothing to do with Julius Caesar). _______________________________________________ This is the MI Programming on the AS400 / iSeries (MI400) mailing list To post a message email: MI400-Zwy7GipZuJhWk0Htik3J/[email protected] To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/mi400 or email: MI400-request-Zwy7GipZuJhWk0Htik3J/[email protected] Before posting, please take a moment to review the archives at http://archive.midrange.com/mi400.
