Is there an easy way to change the date format for the WSSE with suds ? 

With 

token.setcreated(datetime.now())

I get this error :

The timestamp 2010-03-01T16:07:56 in the message is not valid. It must be in this UTC format: yyyy-MM-ddTHH:mm:ssZ

I need to append the 'Z' char at the end of the creation time.

any help would be greatly appreciated
