[ZPT] Modification Time

[Sam Collett]

I get an error when I try this.

Zope Error
Zope has encountered an error while publishing this resource.

Error Type: TALESError
Error Value: exceptions.AttributeError on bobobase_modification_timestrftime
in "", at line 17, column 16

I found the following at the bottom:

File C:\Program
Files\WebSite\lib\python\Products\PageTemplates\ZRPythonExpr.py, line 49, in
__call__
    (Info: template.bobobase_modification_time.strftime('%d/%m/%Y'))
  File Python expression
"template.bobobase_modification_time.strftime('%d/%m/%Y')", line 2, in f
    (Object: guarded_getattr)
  File C:\Program Files\WebSite\lib\python\AccessControl\ZopeGuards.py, line
47, in guarded_getattr
    (Object: bobobase_modification_time)


What does guarded_getattr mean?

Date formatting is peformed internally with the "strftime" method of 
DateTime objects.  You can use it explicitly, like so:

tal:content="python:template.bobobase_modification_time.strftime('%d/%m/%Y')
"

Note that writing "string:${a/b}" is equivalent to, but less efficient 
than, plain "a/b".

Cheers,
