Because you indexed something else that a DateTime object. The index 
will then try to convert it to a DateTime object, and in some caseas 
above this succeeded, and in some cases it didn't. The internal 
DateIndex integer represenations is not the same as time.time().

All of them that actually created an index should work equally fine, 
unless there is a bug in the conversion somewhere. DateTime() is the 
usualy one in Zope, unless you have good reasons not to use it.
