I'm glad you figured out how to proceed.
I wondered why this() was necessary in the first place. Calls to python
procedures usually pass this() implicitly. However, here we have a DTML to
Python call, and I was never very clear about how they work.

Hmm, this is different from what I get. DateTime() reliably gives me the
current time (in all Zope versions I have used). DateTime(0) is supposed to
give 1969/12/31. I haven't a clue why you would get different results.

I think the real question is why it was necessary with Zope 2.1.3.
FWIW, you can also explicily name the title parameter:
<dtml-with "manage_addProduct['Xron']">
<dtml-call expr="manage_addXronDTMLMethod(
'SchedMethodId2',
title='Scheduled Method 2 Title',
executeAt = _.DateTime()+14.0,
periodDays = 0.0,
file = 'Content-Type: text/plain\n\nBANG!!!',
)">
</dtml-with>
I hope others on the list will chime in with their knowledge. I don't think
either of these questions is specifically about Xron itself.
