[Zope-CMF] CachingPolicyManager tests

[Yuppie]

Hi!


This problem normally just appears east of the Atlantic Ocean:


======================================================================
ERROR: test_combined 
(Products.CMFCore.tests.test_CachingPolicyManager.CachingPolicyTests)
----------------------------------------------------------------------
Traceback (most recent call last):

Due to a bug in the DateTime module (see 
<http://collector.zope.org/Zope/484> ), some CachingPolicyManager tests 
fail if your machine's timezone is GMT+X (X > 0). I don't think this bug 
will be fixed soon.

My question:
I don't understand what the CachingPolicyTests actually do. Is
<code>
         self._epoch = DateTime( '1970/01/01' )
</code>
necessary or could it also be an other date?


TIA,
Yuppie
