[flexcoders] Actionscript 3 Cookbook question

[Amy]

Hi, all;

I'm reading in the AS3 Cookbook about working with dates, and it 
frequently mentions ascb.util.DateUtilities.  I'm thinking this is a 
Flash only package, and it seems a lot of the "recipes" depend on it.  
Is there a similar tutorial online that provides a more "Flexy" way to 
do this?

Thanks;

Amy
