Funny enough, my original message was preserved when your system sent me an email saying you don't have enough information. As originally stated, ISO dates should support years in this range and such years are used by astronomers. ------------------------------------------------------------------------ [2007-08-20 16:17:31] mattsch at gmail dot com Description: ------------ I am unable to create dates with years <= -10000 and >= 10000.
