Display Mysql date in flash

Can anyone tell me the optimum way to do the following:

I have a php page that sends xml compiled from data in a mysql table to my swf. The swf is actually an auction and I need to load in the’ end time’ of that item and do a date comparision for a countdown.

So what I’m asking for, in a nutshell, is for the best way to load in a date from a database in such a way that it can be used for date comparisons?

The mysql field is a datetime field. I can modify the format in php to whatever you feel in the best format (I need year, month,day,hour,min, seconds) - but I don’t know what to do with the date once I have it in flash.

example xml: <Item end_time=“2005-04-01 00:00:00” />

can I convert it into a valid date with out string manipulation? since the following doesn’t work (obviously)

my_date = new Date(oXML.firstChild.attributes.end_time)

What I need is to be able to take the current time & substract it from the time in the xml to give me the remaining time.

I hope this makes sense !!!
