[Zope] Simple DTML date-stamp

[Peter Bengtsson]

<dtml-var bobobase_modification_time> should do what you are after.
<dtml-var bobobase_modification_time fmt="%H:%M"> Should return 15:35 for
example.

Take a look at
http://www.zope.org/Members/AlexR/CustomDateFormats
for date and time formats.

I've had som problems with returning the modification date of the right
object if you do like this in standrard_html_footer

Use:
<dtml-with "_.string.split(URL,'/')[-1]">
Current page last modfified: <dtml-var bobobase_modification_time>
</dtml-with>

This should maybe be coupled together with a dtml-try or simply dtml-if, but
I haven't run into problems with it without.

>
> <hr>
> <p>Last modified: <dtml-var date fmt=aCommonZ></p>
> <p><dtml-var ZopeAttributionButton></p>
> </body>
> </html>
