[Zope] language environment changes after a while

[Dirk Datzert]

Hi,

I have detected a problem I can't find rational:

I integrated PublisherProfile product from cvs.zope.org and after zope
starts it writes the time values with formating value %.3f as dotted
values of 0.789 . After a while the format changes to comma values 0,789
.

Where should I search for a bug ? I don't thing that it is a problem of
PublisherProfile product.

Regards,
Dirk
