Politics of TZ changes
by Matt Johnson May 20, 2014

May 20, 2014

The recent changes in Egypt have me thinking. How is it that there isn't some sort of international treaty, law, or agreement about how much notice a government needs to give when making time zone changes? I know almost nothing about international law, but aren't there organizations that coordinate things like trade and commerce that would have something to say about this? It's seems strange to me that we can all agree to let the ITU coordinate UTC while time zones don't seem to be coordinated by any official legal body. Of course, it makes sense that each government should retain its sovereign right to set its time zones as it pleases - but surely something could be done about the process as to which it enacts those changes? I think we can all agree that having a spokesperson give vague details in a media article a week beforehand is not the right way to do things. It's also concerning that people tend to set deadlines based on the date of the change. Not only should time be allowed for the change to be incorporated into the data and distributed to systems, but also people should think about all of the ways that future activities are scheduled based on current knowledge of the tz rules. For example, say you have a weekly scheduled conference call between Egypt and somewhere else in the world. At the moment the Egyptian government announced the change, some of your meeting times became inaccurate. With the change sent out today (2 days before the change), it's not very likely you would receive this update in time to adjust your meeting time. But even if you did get the update, it's quite likely that you would have to reschedule due to conflict with another appointment. For some, this might be an inconvenience. But for others, it could make or break a deal. Cumulatively this could have an economic impact, so one would think it would be in a countries own best interest to give sufficient notice. Perhaps if there were a set of rules, they might be unenforceable and some cases would still slip through the cracks. But at least if there were guidelines defined by some sort of official international governance - we might have a fighting chance. Please share your thoughts and opinions on this topic. What would these rules/guidelines look like? Who might we lobby to enact such a thing?

Propagation latency to end user for 2014c tzdata
by Paul Eggert May 16, 2014

May 16, 2014

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!

Fwd: Politics of TZ changes
by Gwillim Law May 13, 2014

May 13, 2014

The start and end dates of Ramadan are unpredictable only within one day. If the sole religious consideration is to ensure that standard time prevails for the entire month of Ramadan, that can be met by extending the period of standard time so that it encompasses all of the possible duration of Ramadan. The practical consideration of having the time change occur during a weekend could then be met as well. The hitch, of course, is getting the governments concerned to see the value of this expedient.

[tz-announce] 2014c release of tz code and data available
by Paul Eggert May 13, 2014

May 13, 2014

The 2014c release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Changes affecting near-future time stamps Egypt observes DST starting 2014-05-15 at 24:00. (Thanks to Ahmad El-Dardiry and Gunther Vermier.) Details have not been announced, except that DST will not be observed during Ramadan. Guess that DST will stop during the same Ramadan dates as Morocco, and that Egypt's future spring and fall transitions will be the same as 2010 when it last observed DST, namely April's last Friday at 00:00 to September's last Thursday at 23:00 standard time. Also, guess that Ramadan transitions will be at 00:00 standard time. Changes affecting code zic now generates transitions for minimum time values, eliminating guesswork when handling low-valued time stamps. (Thanks to Arthur David Olson.) Port to Cygwin sans glibc. (Thanks to Arthur David Olson.) Changes affecting commentary and documentation Remove now-confusing comment about Jordan. (Thanks to Oleksii Nochovnyi.) Here are links to the release files: ftp://ftp.iana.org/tz/releases/tzcode2014c.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2014c.tar.gz The files are also available via HTTP as follows: http://www.iana.org/time-zones/repository/releases/tzcode2014c.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2014c.tar.gz Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs.

New release of tzdata for Egypt DST change ?
by أحمد المحمودي May 12, 2014

May 12, 2014

Hello, I've seen your git commit. Today is May 12th, yet there is no new release yet of tzdata. I hope you would release it soon enough so that distributions using tzdata would have time to package it (hopefully before May 15th). Thanks... -- ‎أحمد المحمودي (Ahmed El-Mahmoudy) Digital design engineer GPG KeyID: 0xEDDDA1B7 GPG Fingerprint: 8206 A196 2084 7E6D 0DF8 B176 BC19 6A94 EDDD A1B7
