This doesn't have anything to do with the platforms - it
has to do with the fact that you are using two different
Zope versions. Prior to 1.10, calling float() on a DateTime
would return the number of days since Jan. 1, 1901 (gmt).

As of 1.10, this was apparently changed to return the number
of seconds since the epoch (gmt) (note that this is also the
case with int() and long() on a DateTime). I seem to recall a
discussion on the list about this, but I dont remember the 
details (you can probably find them in the archives, though).
