[Zope] compare two dates

Hi all! Sorry for this more python less zope question. Lets say I have this two strings: "13 Feb 2000 20:37:06 GMT" and "Fri, 21 Jan 2000 11:29:10 +0000" I want to compare them has dates and not strings with the built-in cmp() func. What type of cast, conversion can I do. Or what module can I use for this. Is really anything already done, I do not want to go scratchy :-) Thanxs, Júlio ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
