[Zope] Date Manipulation

[Luke Duff]

Thanks for the help, but...

My problem is a little bit harder than that. The data in field2 is date *and* 
time. So like this:

field1 field2
------ ---------------
red    3/1/99 10:00 AM
blue   3/1/99 11:00 AM
green  3/1/99 03:00 PM
brown  3/2/99 10:00 AM
yellow 3/2/99 04:30 PM

I've seen in the guide where you can format a data field when outputting, but 
how do actually extract the day-of-the-month number and put it in a temp 
variable. The pseudo-code I've used before to do this before is:

tempday = 0
for each record
  if tempday<>dayofmonth(datefield) then
     print out a header
  print out other fields
  tempday = dayofmonth(datefield)
next

I'm just having a little trouble translating that into DTML. Creating a simple 
temporary variable seems overly complicated.

You can use the #in tag's grouping features for this.
