[Zope] DateTime under phyton script

[Kerekes Lajos]

Hi!

I have a form. It contains 3 drop-down boxes, named start_year:int,
start_month:int, start_day:int.
How can I use them, to make a datum object under phyton script?
I try

starttime = DateTime(container.REQUEST.start_year,
container.REQUEST.start_month, container.REQUEST.start_day)

but it gives an error

Error Type: TypeError
Error Value: illegal argument type for built-in operation

Could anybody help me?

  Thanks:
