[Zope] Splitting a datetime string into a date string and a time string

[Tino Wildenhain]

Hi Gitte,

obviously you have to have DateTime objects to manipulate
with them. If you convert them to strings beforehand you
are not able to use their methods later :)

If its a DateTime field in your database and not a
string field, the result must be a DateTime object
with all its methods, including strftime()
If not, you have to instantiate a DateTime object from
string like this: DateTime(date_time_as_string)

What are you doing with filenames in DTML anyway?
If you mean object IDs, you can construct it like this:

<dtml-let objID="_.DateTime(time_as_string).strftime('%Y%m%d')">
<dtml-var objID>
</dtml-let>

Omit this DateTime instantiation if you have a real datetime-object
from your database as it should be.

Regards
Tino Wildenhain
