[flexcoders] What is the best way to add a day to a date?

[Mark]

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.  What 
is the best way to do that?  Right now I'm working it out this way:

s = chartDates.getItemAt(0).globalDeadline;
a = s.split("/");
newDate = a[0]+"/"+a[1]+"/"+(Number(a[2])+1);

But I'm pretty sure this isn't right.

Can someone help out with the code?

Thanks
