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

June 13, 2014

The 2014e 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's 2014 Ramadan-based transitions are June 26 and July 31 at 24:00. (Thanks to Imed Chihi.) Guess that from 2015 on Egypt will temporarily switch to standard time at 24:00 the last Thursday before Ramadan, and back to DST at 00:00 the first Friday after Ramadan. Similarly, Morocco's are June 28 at 03:00 and August 2 at 02:00. (Thanks to Milamber Space Network.) Guess that from 2015 on Morocco will temporarily switch to standard time at 03:00 the last Saturday before Ramadan, and back to DST at 02:00 the first Saturday after Ramadan. Changes affecting past time stamps The abbreviation "MSM" (Moscow Midsummer Time) is now used instead of "MSD" for Moscow's double daylight time in summer 1921. Also, a typo "VLASST" has been repaired to be "VLAST" for Vladivostok summer time in 1991. (Thanks to Hank W. for reporting the problems.) Changes affecting commentary tz-link.htm now cites RFC 7265 for jCal, mentions PTP and the draft CalDAV extension, updates URLs for TSP, TZInfo, IATA, and removes stale pointers to World Time Explorer and WORLDTIME. Here are links to the release files: ftp://ftp.iana.org/tz/releases/tzcode2014e.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2014e.tar.gz The files are also available via HTTP as follows: http://www.iana.org/time-zones/repository/releases/tzcode2014e.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2014e.tar.gz Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs. Copies of these signatures are appended to this message.

Weeks in Daylight Saving Time
by Hank W. June 8, 2014

June 8, 2014

I just answered a question on Wiki Answers regarding how many weeks are in Daylight Saving Time. I dont know if any of you ever figured this out, so I thought some of you might find this interesting. Hank W. of Austin The duration of Daylight Saving Time (a.k.a. Summer Time) ranges from a low of 12 weeks in Fiji to a high of 34 weeks in North America and Chile (for reference, 3 months = 13 weeks, 6 months = 26 weeks, and 9 months = 39 weeks).... 34 weeks/year : * United States * Canada * Cuba * Haiti * Bermuda * Bahamas * Turks & Caicos * part of Greenland * Saint-Pierre & Miquelon * parts of Mexico 33 or 34 weeks/year : * Chile * Easter Island * part of Antarctica 30½ or 31½ weeks/year in Israel 30 or 31 weeks/year : * Europe, except Russia, Belarus and part of Ukraine * Azerbaijan * Turkey * Cyprus * Jordan * Lebanon * Syria * Namibia * most of Greenland * Azores * Canary Islands * Madeira Islands 29 or 30 weeks/year in most of Mexico 27 or 28 weeks/year : * New Zealand * Chatham Islands * Samoa * part of Antarctica 26½ weeks/year in Iran 26 or 27 weeks/year in Australia 25½ to 31 weeks/year in Morocco and Western Sahara 25 or 26 weeks/year in the Palestinian Territories 24 or 25 weeks/year in Paraguay 22 or 23 weeks/year in Uruguay 17½ to 22 weeks/year in Egypt 17 to 19 weeks/year in Brazil 12 or 13 weeks/year in Fiji

Yacht crew member killed after daylight-saving error
by Paul Eggert June 5, 2014

June 5, 2014

Here's a sobering reminder of one of the downsides of daylight saving time. Last month the Australian Transport Safety Bureau published its investigation into a fatal accident on 2013-02-08 at 13:45 +1100, as the motor yacht Calliope transited the Glebe Island Bridge in Rozelle Bay, Sydney Harbour. When the ship's master calculated tidal conditions for the transit, he determined that low tide would be at 13:20 local time. However, he forgot to allow for daylight saving time, and the actual low tide was at 14:20. The miscalculation contributed to a botched transit; as the crew positioned a fender to control contact with the bridge structure, an assistant engineer was caught between the yacht's fashion plate and a bridge-mounted fender, was pulled overboard, and died. Crane E. Crewman crushed to death in yacht crash after captain misjudged tide times when the clocks changed.
