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

Hello Team, Could you please update us? Regards, Shageaa From: Mohamed Shageaa Sent: Sunday, May 11, 2014 5:25 PM To: 'tz(a)iana.org' Subject: Re: Re: [tz] Egypt to change back to Daylight system! Dears, Hope you are doing well! With reference to the below URL, we need to know the following: http://mm.icann.org/pipermail/tz/2014-May/020869.html * When the package will be released? * Will it include the Java updater tool? * Will it include the zic rule file? * As per the shared rules, I can see that the time change will be as following, o On 15th of May at 00:00:00, one hour will be added, changing the time to 01:00:00, is that correct? o If yes, then this won't be our case in Egypt, since the time will be changed on the 16th of May not the 15th of May. +Rule Egypt 2014 only - May 15 0:00s 1:00 S +Rule Egypt 2014 only - Jun 29 0:00s 0 - +Rule Egypt 2014 only - Jul 29 0:00s 1:00 S +Rule Egypt 2014 max - Sep lastThu 23:00s 0 - Regards, Shageaa

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 ----
