[flexcoders] Re: What is the best way to add a day to a date?
Sorry, first post didn't come through properly. Try this: var origDateString:String = 2008/12/31; var dateItems:Array = origDateString.split(/); var newDate:Date = new Date(dateItems[0], Number(dateItems[1])-1, Number(dateItems[2])+1); var newDateString:String = newDate.getFullYear() + / + (newDate.getMonth() + 1) + / + newDate.getDate(); Ryan --- In flexcoders@yahoogroups.com, Mark [EMAIL PROTECTED] wrote: I'm getting dates in my XML formatted like this: 2008/12/20 In some cases in my Flex app I need to add 1 day to that date.

Re: [flexcoders] Re: What is the best way to add a day to a date?
seems doing this you could easily end up with 2008/12/32 :) I'd parse the data, then create a Date object. Adding a day to a Date should be as simple as myDate.time += (24 * 60 * 60 * 1000); hth Scott Scott Melby Founder, Fast Lane Software LLC http://www.fastlanesw.com rmarples wrote: --- In flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com, Mark [EMAIL PROTECTED] wrote: I'm getting dates in my XML formatted like this: 2008/12/20 In some cases in my Flex app I need to add 1 day to that date.

It's not that simple, because of Daylight Savings Time. Try the following on a machine with the timezone set to something that follows DST: var ms:Number = 24*60*60*1000; var d:String = 2008/11/02; var newDate:Date = new Date(Date.parse(d)+ms); You'll get the same day, 2008/11/02, because Nov 2 2008 will be a 25- hour day in some locations due to the clocks being set back. You'd need to convert to UTC before doing the math, or check the timezone of the dates with getTimezoneOffset() and adjust accordingly if needed. --- In flexcoders@yahoogroups.com, Kevin Aebig [EMAIL PROTECTED] wrote: Yeah, that works too... =] !k -Original Message- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Muzak Sent: Thursday, February 07, 2008 4:16 PM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] What is the best way to add a day to a date? or: var ms:Number = 24*60*60*1000; var d:String = 2008/12/20; var newDate:Date = new Date(Date.parse(d)+ms); - Original Message - From: Kevin Aebig [EMAIL PROTECTED] To: flexcoders@yahoogroups.com Sent: Thursday, February 07, 2008 6:19 PM Subject: RE: [flexcoders] What is the best way to add a day to a date?

Re: [flexcoders] Re: What is the best way to add a day to a date?
Works fine here using 2008/11/02 as the starting date, but that's probably because winter time kicks in on a different date here (which I don't know). Summer time kicks in on 2008/03/30 so I tried that instead. Notice that the new date has 1 hour added. I guess when using the winter time it would subtract 1 hour, resulting in the same date as the original. // tested var ms:Number = 24*60*60*1000; var d:String = 2008/03/30; var newDate:Date = new Date(Date.parse(d)+ms); trace(new Date(Date.parse(d))); trace(newDate); //output Sun Mar 30 00:00:00 GMT+0100 2008 Mon Mar 31 01:00:00 GMT+0200 2008 Gotta luv date manipulations.. fun fun.. - Original Message - From: Doug Lowder [EMAIL PROTECTED] To: flexcoders@yahoogroups.com Sent: Friday, February 08, 2008 1:56 AM Subject: [flexcoders] Re: What is the best way to add a day to a date?
