[Zope] what to put into DateIndexes?

[Jürgen Herrmann]

hi!

short question: what do i have to "put into" dateindexes? i tried to
feed them with DateTime instances, ints, floats, strings - to no avail!

the index list of the catalog shows "# objects: 0", though i have some
objects in it, maybe you'd like to see the following screenshot:
http://apis-intern.com/DateIndex.png - the rightmost colum shows what
i've tried to put in there, the empty columns were initialized with
DateTime instances, which don't show up at all here...

plz help - i couldnt even find something about this trivial issue
in the zopebook or elsewhere, they just show how dateindex hast to be
queried...

regards, juergen herrmann
