[Zope] bobo_mod_time difference in zcat vs object

[Chris McDonough]

Hi Joel,

Because bobobase_modification_time is kept as metadata, it isn't updated
until you reindex the object.

To do this, when an object is changed, immediately reindex it the catalog by
calling:

<dtml-call "yourcatalog.catalog_object(object, object.getPhysicalPath())">

In versions of Zope 2.3.1b2 and greater, you can just do:

<dtml-call "yourcatalog.catalog_object(object)">

... and it will do the right thing.
