--- Comment #9 from Darin Adler <darin at apple.com> ---
I think the issue is that finding time offsets has always been slow, and involves calling underlying platform APIs. And our caching is inadequate to mitigate that. And it also seems that websites that don’t need this expensive operation end up asking for it accidentally.

It would be easy to fix this slowdown by restoring the old behavior, and much harder to fix it by optimizing local time computations.
