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

Troll rule parsing issue
by David Braverman May 4, 2014

May 4, 2014

Hi, First, we don't use zic; we use our own .NET tzinfo parser. I would expect zic doesn't have the problem we've encountered. The most recent change of the Antarctica file (2014-03-21, commit 6285081) introduced three leading spaces before the three leading tab characters at line 267 (second line of the Antarctica/Troll zone definition). Because of the data before the first tab character, our system has an off-by-one error parsing the rest of the line, and doesn't recognize it as a zone definition line. What is the rule regarding continuation lines on zone definitions? We split lines into arrays by tab, which fails in this case where there are leading spaces before the first tab. Since this works in all other cases, is this an error in the data? Or should we follow a different semantic rule? Thanks. David Braverman Chicago

zic changes (1/2)
by Arthur David Olson May 1, 2014

May 1, 2014

A possibility mentioned last year at the time of the Macquarie fix: here's a more general fix for zic.c. For clarity, it comes in two pieces. This first piece simply rolls back the Macquarie-specific changes to zic.c; it's both attached and appears in mangled form below. These changes are relative to the git repository version. @dashdashado 1.1 2838 lines 1.2 2805 lines *** /tmp/,azic.c 2014-05-01 01:51:26.531315400 -0400 --- /tmp/,bzic.c 2014-05-01 01:51:26.640515600 -0400 *************** *** 1480,1490 **** fromi = 0; while (fromi < timecnt && attypes[fromi].at < min_time) ++fromi; ! /* ! ** Remember that type 0 is reserved. ! */ ! if (isdsts[1] == 0) ! while (fromi < timecnt && attypes[fromi].type == 1) ++fromi; /* handled by default rule */ for ( ; fromi < timecnt; ++fromi) { if (toi != 0 && ((attypes[fromi].at + --- 1480,1487 ---- fromi = 0; while (fromi < timecnt && attypes[fromi].at < min_time) ++fromi; ! if (isdsts[0] == 0) ! while (fromi < timecnt && attypes[fromi].type == 0) ++fromi; /* handled by default rule */ for ( ; fromi < timecnt; ++fromi) { if (toi != 0 && ((attypes[fromi].at + *************** *** 1589,1599 **** } thistimelim = thistimei + thistimecnt; thisleaplim = thisleapi + thisleapcnt; ! /* ! ** Remember that type 0 is reserved. ! */ ! writetype[0] = FALSE; ! for (i = 1; i < typecnt; ++i) writetype[i] = thistimecnt == timecnt; if (thistimecnt == 0) { /* --- 1586,1592 ---- } thistimelim = thistimei + thistimecnt; thisleaplim = thisleapi + thisleapcnt; ! for (i = 0; i < typecnt; ++i) writetype[i] = thistimecnt == timecnt; if (thistimecnt == 0) { /* *************** *** 1609,1619 **** /* ** For America/Godthab and Antarctica/Palmer */ - /* - ** Remember that type 0 is reserved. - */ if (thistimei == 0) ! writetype[1] = TRUE; } #ifndef LEAVE_SOME_PRE_2011_SYSTEMS_IN_THE_LURCH /* --- 1602,1609 ---- /* ** For America/Godthab and Antarctica/Palmer */ if (thistimei == 0) ! writetype[0] = TRUE; } #ifndef LEAVE_SOME_PRE_2011_SYSTEMS_IN_THE_LURCH /* *************** *** 1663,1688 **** } #endif /* !defined LEAVE_SOME_PRE_2011_SYSTEMS_IN_THE_LURCH */ thistypecnt = 0; - /* - ** Potentially, set type 0 to that of lowest-valued time. - */ - if (thistimei > 0) { - for (i = 1; i < typecnt; ++i) - if (writetype[i] && !isdsts[i]) - break; - if (i != types[thistimei - 1]) { - i = types[thistimei - 1]; - gmtoffs[0] = gmtoffs[i]; - isdsts[0] = isdsts[i]; - ttisstds[0] = ttisstds[i]; - ttisgmts[0] = ttisgmts[i]; - abbrinds[0] = abbrinds[i]; - writetype[0] = TRUE; - writetype[i] = FALSE; - } - } for (i = 0; i < typecnt; ++i) ! typemap[i] = writetype[i] ? thistypecnt++ : 0; for (i = 0; i < sizeof indmap / sizeof indmap[0]; ++i) indmap[i] = -1; thischarcnt = 0; --- 1653,1660 ---- } #endif /* !defined LEAVE_SOME_PRE_2011_SYSTEMS_IN_THE_LURCH */ thistypecnt = 0; for (i = 0; i < typecnt; ++i) ! typemap[i] = writetype[i] ? thistypecnt++ : -1; for (i = 0; i < sizeof indmap / sizeof indmap[0]; ++i) indmap[i] = -1; thischarcnt = 0; *************** *** 2105,2115 **** updateminmax(leapminyear); updateminmax(leapmaxyear + (leapmaxyear < ZIC_MAX)); } - /* - ** Reserve type 0. - */ - gmtoffs[0] = isdsts[0] = ttisstds[0] = ttisgmts[0] = abbrinds[0] = -1; - typecnt = 1; for (i = 0; i < zonecount; ++i) { zp = &zpfirst[i]; if (i < zonecount - 1) --- 2077,2082 ----

re : Time zones in Ukraine
by Nickolay Olshevsky April 19, 2014

April 19, 2014

Thank you guys for prompt answer, now I got it. Will at least go and read what was that Rutenia :) The another idea would be to keep somewhere list of active timezones along with tz database, but I understand that it would be almost impossible to add corresponding APIs everywhere. -- Best regards, Nickolay Olshevsky
