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

I have also encountered problems with the date code in WebKit. I was
able to fix the bugs I care about ( windows port crashed ) by upgrading
to the latest code from WebKit.org. Since it sounds as though you are
an AJAX developer trying to get your app working in Safari, that might
not help you too much. The date object's implementation seems to have
been totally redone recently. I would not be surprised if the old code
is broken for dates outside of the "compatible range" ( 1970/1/1 -
sometime in 2038 ) in one way or another.
If you want to see the C++ code in question look at:
User kmccullo seems to be the person who has submitted most of the
changes in this area recently.
Hope this helps,

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
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..
