HI GOZ,

I have a problem with the float method from DateTime module !! It seems that Linux and WIN32 platform(NT) do not give the same result. Is there an explanation?

NT (Zope 1.1.02) -----------------------

...

...

...

z=DateTime.DateTime('1999/02/25 0:00pm US/EASTERN') z DateTime('1999/02/25 12:00:00 US/Eastern') float(z) 919962000.0

LINUX (Zope 1.9) ------------------------

...

...

...

z=DateTime.DateTime('1999/02/25 0:00pm US/EASTERN') z DateTime('1999/02/25 12:00:00 US/Eastern') float(z) 35849.7083333

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).
