[Zope-dev] Weird test failures with DateTime

[Philipp von Weitershausen]

Hi,

I've recently been seeing weird DateTime test failures on all Zope 2
branches since 2.7 (see below). Any idea what I'm doing wrong? My system
is OSX 10.3 with a self-compiled Python 2.4.1 (through darwinports). My
system timezone, as you can see, is GMT+0800 (Beijing time).
