This _is_ the folder's bobobase_modification_time you're getting. A folder
is largely a container.  Aside from creating or deleting it you can only
change it by changing what it contains.  Changing a folder's properties or
deleting a file it contains also updates it's bbb_mod_time.

By calling m/m you've bound m as the client object for the method
m.  <dtml-var id> will give you m's id, <dtml-var title> will give you m's
title.  DTML Methods are designed to give you access to the attributes of
the object they are called on.

If you make m a DTML Document it will give it's own bbb_mod_time no matter
how you call it.
