I think Bart's suggestion is a good one. I suspect the problem may be a local time zone offset issue. The Date object stores a date value as an integer representing the number of milliseconds since the "Epoch" (midnight Jan 1, 1970 UTC). If you don't use UTC dates rigorously, you leave yourself open to the vagaries of time zone offset problems.
In other words, the time zone setting on your computer matters when you create a date object the way you described below. You can test this by running the following code, then running it again after adjusting the time zone setting on your computer: // results from San Francisco var checkin = new Date(2006,5,20); trace(checkin); // Tue Jun 20 00:00:00 GMT-0700 2006 trace(checkin.getTime()); // 1150786800000 // results when Time zone is set to London trace(checkin); // Tue Jun 20 00:00:00 GMT+0100 2006 trace(checkin.getTime()); // 1150758000000 Notice that you actually get different millisecond values. Also notice that the London local time version of new Date(2006,5,20) will always be interpreted as June 19 in the US because if it's midnight in London, it's always the day before here in the US. The best way to avoid this problem is to always work with UTC dates. Try the same test above, using the Date.UTC() method, and you'll find that the millisecond value is the same no matter which time zone setting you use: var checkinUTC = new Date(Date.UTC(2006,5,20)); trace(checkinUTC); // [June 20, 2006 in your local time] trace(checkinUTC.getTime()); // 1150761600000 Just be sure to always use the "UTC" versions of the Date class methods and properties, or you'll experience the same problem: trace(checkinUTC.getUTCFullYear()); // 2006 trace(checkinUTC.getUTCMonth()); // 5 trace(checkinUTC.getUTCDate()); // 20 HTH, Francis > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:flashcoders- > [EMAIL PROTECTED] On Behalf Of Bart Wttewaall > Sent: Tuesday, May 02, 2006 5:15 PM > To: Flashcoders mailing list > Subject: Re: [Flashcoders] Date Object Problem > > I'm not sure if it'll solve your problem, but you might want to check > out Date.UTC > > var maryBirthday_date:Date = new Date(Date.UTC(1974, 7, 12)); > trace(maryBirthday_date); > > I'm not sure what it does (something with universal time), since the > documentation is quite cryptic, but perhaps it's related..? > > Good luck. > > 2006/5/2, Nick McNeill <[EMAIL PROTECTED]>: > > First off, long-time member of this list and have gained a wealth of > > knowledge from the wisdom here.
