[Zope] DateTime(), locale, summertime etc.

I have a product where I convert some external datetimes to zope DateTime() objects. I save them as UTC as zopes DateTime does by default. But when these are rendered, the time is offset by two hours. A few weeks ago, it wasn't that bad. It was only one hour, but then summertime came along ;-) So it seems that there is some magic going on where Zope tries to take locale and summertime into account. Is this configurable somewhere. In Zope, Python, as a command switch or in a config file? -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science
