- Anyone else?

- Yep. timezone.el can't handle certain date formats. I fixed it in my
- version and sent it to the gnus bug lists, and apparently some sort of
- fix will be in the most recent updates if it's not already in this new
- 3.14.3 beta release.
-
- Here's a new timezone.el if you want to fix it now. Make sure to crop my
