Looks like it's not a bug, but a feature. Here's the official info from Netscape's developer's pages: http://developer.netscape.com/docs/manuals/js/core/jsref/date.htm#1194138 getYear Returns the year in the specified date according to local time. JavaScript 1.3: deprecated; also, getYear returns the year minus 1900 regardless of the year specified ECMA version ECMA-262 Description getYear is no longer used and has been replaced by the getFullYear method. The getYear method returns the year minus 1900; thus: For years above 2000, the value returned by getYear is 100 or greater. For example, if the year is 2026, getYear returns 126. For years between and including 1900 and 1999, the value returned by getYear is between 0 and 99. For example, if the year is 1976, getYear returns 76. For years less than 1900 or greater than 1999, the value returned by getYear is less than 0. For example, if the year is 1800, getYear returns -100. To take into account years before and after 2000, you should use Date.getFullYear instead of getYear so that the year is specified in full. ---------------------------------------------------------------------- http://developer.netscape.com/docs/manuals/js/core/jsref/date.htm#1193607 getFullYear Returns the year of the specified date according to local time. Implemented in JavaScript 1.3 ECMA version ECMA-262 Description The value returned by getFullYear is an absolute number. For dates between the years 1000 and 9999, getFullYear returns a four-digit number, for example, 1995. Use this function to make sure a year is compliant with years after 2000. Use this method instead of the getYear method. ==== So, apparently Microsoft does it wrong, so it works, and Netscape does it right, so it doesn't. *grin* 'course, it'll be interesting to see how the press reports on all the sites showing addresses like "Jan 1, 19100" due to this little item..... --Lloyd On Sat, 1 Jan 2000, Lloyd Taylor wrote: > Date: Sat, 1 Jan 2000 21:38:23 -0800 (PST) > From: Lloyd Taylor <[email protected]> > To: Will Pierce <[email protected]> > Cc: [email protected] > Subject: Re: Netscape JavaScript getYear() problem?
