To complete my last post: the date obtained with ns_time is formatted using util::cookietime that use ns_httptime; ns_httptime will format the date according to the locale of the system where aolserver is running.
On the other hand, I've tested again on safari (version 2.0.1, Tiger) but this time with our oacs-5-1 based installation and there is the same problem. I'm not sure that this problem exists with previous versions of Safari, that's maybe why you didn't notice it before.
