[webkit-dev] Stumped by Date() results in Safari

[Jason White]

Hmm. Yes, that's it. The machines having the problem all run 10.3.9
and Safari reports being 1.3.2. I suppose it could be a problem that
was fixed, but since I think people would have noticed this I've got a
feeling that it's probably something external to Safari.. I'm just
really puzzled by why it would only affect that browser on the very
same machines.

I'm in a situation where I have to support Safari for various reasons,
however, I'm not really an expert on it.. so if someone spots a big
newbie mistake please accept my apologies! As I said, I tried to find
the answer in documentation but got nowhere. Thanks for sharing the
bandwidth and time..
