Sorry, I was wrong, at least partially!

The fact, that "ZopeTime" returns an unprotected DateTime object,
does of cause not mean that "ZopeTime" itself is unprotected.

After your message, I reexamined your problem:

 * "ZopeTime" is defined in "OFS.Application.Application",
   i.e. the top level application object.

 * "ZopeTime" apparently is not protected by an explicit
   permission (neither mentioned in an "__ac_permissions__"
   nor is there a "ZopeTime__roles__" attribute nor
   is there a new SecurityManager assertion about
   "ZopeTime".

   As I understand Zope 2.2 security, this should mean
   "ZopeTime" is inaccessible from DTML.
   
 * However, magically, "ZopeTime" is protected by "Access Contents
   Information". 

I can not tell you why.
Both is astonishable:
  * that it is accessible by DTML at all
  * why "Access Contents Information" is required.

Apparently, the Zope security still has some hidden magic.
