Very cool! And I might add - if only *Windows* was updated so seamlessly! For those interested, you need to apply KB2967990 on Windows. I'm keeping a list on my blog of this and the various dependent updates:http://codeofmatt.com/2014/05/15/egypt-goes-back-to-daylight-saving-time/ Cheers!-Matt

In what must be a speed record for my personal desktop, the 2014c release of tzdata was installed at 22:13:49 UTC yesterday, which is only 25780 seconds (roughly 7 hours 10 minutes) after the announcement was sent to tz-announce at 15:05:51 UTC.

I got this entirely through the normal channels by doing the software updates I normally do from my supplier Canonical; the desktop runs Ubuntu 14.04 LTS, the current long term stable release. If I understand the process correctly, Debian had the patch prepared by 17:05:45 UTC yesterday, 7296 seconds (roughly 2 hours 3 minutes) after the announcement, and Ubuntu followed suit by 17:53:46 UTC yesterday, 10177 seconds (roughly 2 hours 50 minutes) after the announcement, though I don't know when the prepared patches were actually published.

If only our cell phones and servers were updated so quickly!
