Just curious, has anybody considered using M A Lemburg's mxDateTime package (http://starship.skyport.net/~lemburg/mxDateTime.html) for dates and times in Zope? It's versatile and relatively mature. No idea what the license is like, but I'll wager it is Zope-compatible. I get the impression that M-A has already dealt with a lot of the issues being discussed. -- Tim Gilbert -:- Tonic Corp -:- tim@tonic.to
