Jordan back from DST - reverting to UTC+2
Jordan Times and other sources say that Jordan is going back to UTC+2 on 2013-12-19 at midnight: http://jordantimes.com/govt-decides-to-switch-back-to-wintertime (in English) Official, in Arabic: http://www.petra.gov.jo/public_news/Nws_NewsDetails.aspx?Menu_ID=&Site_Id=2&... We assume they mean going back from 2013-12-20 00:00 to 2013-12-19 23:00, but it could also be one hour later, which is what they have normally done in the past. Based on the wording in the article, they call it coming back to winter time, so I think it would be best to change the Rules for Jordan and Zone for Amman, so it says DST started back in March 2012, never ended for the 2012/2013 winter and lasted all to December 2013.

Thanks for the heads-up. I'm inclined to guess that the December 20 transition will be at midnight standard time, not midnight DST, as that's been their common pattern for fall-back transitions. It's a guess either way, of course, but here's a proposed patch. I've pushed this to the experimental github repository. Sounds like it's time for a new release soon.

It's a guess either way, of course, but here's a proposed patch. There is a new article from the government, this time in English: http://www.petra.gov.jo/Public_News/Nws_NewsDetails.aspx?lang=2&site_id=1&Ne...
It says midnight for the coming one and 1:00 for the ones in the future (and they will use DST again next year, using the normal schedule). So based on this, and also that the other sources say "midnight", I would actually think they are planning to change one hour earlier than normal, but just this time.

Thanks for the further heads-up. I've pushed this patch to the experimental github version.
