------- Additional Comments from David Kilzer (ddkilzer) <ddkilzer at webkit.org>
If the user changes time zones without restarting a WebKit application like
Safari, the cached UTC offset will cause JavaScript to report the wrong time
zone and/or the wrong time.  The simple solution is to stop caching the UTC
offset and calculate it every time.  That's what this patch does.

Note that no performance testing has been done.
