[Zope] dtml methods and properties

[Willem Broekema]

As a DTML method is said to work with the properties of the object it
is called at:

DTML method "m":
 <dtml-var bobobase_modification_time>

<root folder of site>/m 
 displays the date/time when the last change happened to any file
 in the root folder

<root folder>/m/m
 displays last change date/time of method m

Why does the method not display it's modification time on the first
occasion? Or: why does it not give the folder's modification time
on the second occasion?
