[Zope] R: [Zope] DateTime and ISO-dates

I have some problems with DateTime in Zope. I generally want dates in the form 'YYYY-MM-DD'. But I can't figure out an easy way to get this with DateTime objects. There is a ISO method that produces both date and time: 'YYYY-MM-DD HH:MM:SS'. But nothing to get only the date.

Perhaps one could wish for some addtions to the DateTime class. Some possibilities are, in order of preference:

1. Configurable default data format. 2. An ISODate method. 3. strftime method that uses localtime and not gmtime.

<dtml-call "REQUEST.set('a',_.DateTime())"> <dtml-call "REQUEST.set('your_date','%s-%s-%s' %(a.year(),a.mm(),a.dd()))"> <dtml-var your_date> Is already tested. PM
