You're trying to change the zclass properties after creating it but
you're not passing in a valid date time string and hence you're getting
this error. Make sure the string you're passing in conforms to a date
time format. (check ZOPE_HOME/lib/python/DateTime/DateTime.py for the
supported formats), or just cast it explicitly like <dtml-call
"REQUEST.set('date', DateTime('datestring'))">. I've noticed some
behavior earlier today where i change all my zclass properties in a
manage_changeProperties (depends on where) even ones not listed in the
request. if this is your problem and you don't have date_time string set
in the REQUEST you can try explicitly passing in a dummy date time
string (ZopeTime or distant past), or setting it to its default value, 

<dtml-with object>
<dtml-call "REQUEST.set('Date', date)">
</dtml-with>

i'd chuck this into the Collector/Tracker.

i'm sure others have good solutions.
