[Zope-dev] ZMailIn patch (index 'date' as DateTime object)

[Jean Jordaan]

Hi Andy & all

There I was, trying to select last week's mail messages from
the ZMailInCatalog, when I realized that the 'date' index was
a simple string. 

Here's a patch, adding a property 'datetime', which can be 
used as an index of type DateTime. 

Anything I'm missing here? In particular, I'm not sure I
understand what 'sortableDate' is meant for. It's a string 
like this::

  str('%04d%02d%02d%02d%02d%02d' % (dateTuple[0],dateTuple[1],
      dateTuple[2],dateTuple[3],dateTuple[4],dateTuple[5]))

But it's still a string, and can't be used in comparisons 
with DateTimes. Why not just use 'datetime', also sortable?

Regards,
Jean Jordaan
