RE: America/Chicago zone vs mktime w/tm_isdst!=-1
by Olson, Arthur David (NIH/NCI) 06 Dec '03

06 Dec '03

The strange Chicago behavior occurs because for a few months back in 1936 Chicago switched to using Eastern Standard Time; mktime ended up using this information when trying to do a DST correction. The change below should "fix" things; it convinces mktime to work temporally backward through time adjustments that have been used in an area when trying to do a DST correction. (Of course if you really did start out with a 1936 time this is the wrong thing to do, but that's fairly unlikely.) --ado ------- localtime.c ------- *** /tmp/geta23340 Fri Nov 28 12:10:57 2003 --- /tmp/getb23340 Fri Nov 28 12:10:57 2003 *************** *** 5,11 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)localtime.c 7.76"; #endif /* !defined NOID */ #endif /* !defined lint */ --- 5,11 ---- #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)localtime.c 7.77"; #endif /* !defined NOID */ #endif /* !defined lint */ *************** *** 1503,1508 **** --- 1503,1513 ---- register time_t t; register const struct state * sp; register int samei, otheri; + register int sameind, otherind; + register int i; + register int nseen; + int seen[TZ_MAX_TYPES]; + int types[TZ_MAX_TYPES]; int okay; if (tmp->tm_isdst > 1) *************** *** 1536,1545 **** if (sp == NULL) return WRONG; #endif /* defined ALL_STATE */ ! for (samei = sp->typecnt - 1; samei >= 0; --samei) { if (sp->ttis[samei].tt_isdst != tmp->tm_isdst) continue; ! for (otheri = sp->typecnt - 1; otheri >= 0; --otheri) { if (sp->ttis[otheri].tt_isdst == tmp->tm_isdst) continue; tmp->tm_sec += sp->ttis[otheri].tt_gmtoff - --- 1541,1560 ---- if (sp == NULL) return WRONG; #endif /* defined ALL_STATE */ ! for (i = 0; i < sp->typecnt; ++i) ! seen[i] = FALSE; ! nseen = 0; ! for (i = sp->timecnt - 1; i >= 0; --i) ! if (!seen[sp->types[i]]) { ! seen[sp->types[i]] = TRUE; ! types[nseen++] = sp->types[i]; ! } ! for (sameind = 0; sameind < nseen; ++sameind) { ! samei = types[sameind]; if (sp->ttis[samei].tt_isdst != tmp->tm_isdst) continue; ! for (otherind = 0; otherind < nseen; ++otherind) { ! otheri = types[otherind]; if (sp->ttis[otheri].tt_isdst == tmp->tm_isdst) continue; tmp->tm_sec += sp->ttis[otheri].tt_gmtoff - -----Original Message----- From: tz-request(a)lecserver.nci.nih.gov [mailto:tz-request@lecserver.nci.nih.gov] On Behalf Of Olson, Arthur David (NIH/NCI) Sent: Tuesday, November 25, 2003 7:40 AM To: Tz (tz(a)elsie.nci.nih.gov) Subject: FW: America/Chicago zone vs mktime w/tm_isdst!=-1 Dan Nelson is not on the time zone mailing list; direct replies appropriately. --ado -----Original Message----- From: Dan Nelson [mailto:dnelson@allantgroup.com] Sent: Monday, November 24, 2003 6:23 PM To: tz(a)lecserver.nci.nih.gov Subject: America/Chicago zone vs mktime w/tm_isdst!=-1 Here's an interesting problem.

America/Chicago zone vs mktime w/tm_isdst!=-1
by Dan Nelson 24 Nov '03

Here's an interesting problem. Usually when mktime() is called with tm_isdst set to 0 or 1, it will interpret the original time as being either in standard or daylight time according to tm_isdst, and update the resulting time_t value (and the struct tm) if the DST flag was wrong. This doesn't seem to happen with the America/Chicago zone. I've attached a simple program that passes three struct tm's to mktime, with three values of tm_isdst each. For most zones, the first and last times change depending on what value of tm_isdst is passed in. For America/Chicago, it looks like tm_isdst is ignored.

Note that when referenced in recommendations and articles published in past years, this document may have been referred to as the IERS Conventions (2000). The content of the web page above is now frozen to the present version of the IERS Conventions. Comments and proposals for their future evolution are invited through the Questionnaire below. Comments may also be sent directly to the principal scientists of the IERS Conventions center Dennis McCarthy (dmc(a)maia.usno.navy.mil) and Gerard Petit (gpetit(a)bipm.org) Questionnaire from the IERS Conventions Center The IERS Conventions (2003) are available at http://maia.usno.navy.mil/conv2000.html or in printed form as IERS Technical Note 32. The IERS Conventions Center invites questions, comments, remarks or suggestions of any type concerning this document specifically in the following areas. The bulleted items are meant to guide but not limit responses. 1. IERS Conventions (2003) 1.1 Content * Value as a general reference document * Value of changes in 2003 vs. Conventions (1996) * Structure of the document * Problems or errors discovered * Models that should be replaced or added * Implementation of associated software 1.2 Availability * Paper edition (forthcoming) * Web site and electronic formats 2. Future IERS Conventions Plans are to continue to have "paper editions," i.e. a reference edition with a label, published at intervals of several years or whenever a major change is needed, especially one that affects the definition of the reference systems or the principal characteristics of the realized frames. Upgrades containing corrections, introduction of explanatory parts, new software implementations, addition of models that do not affect "the principal characteristics" etc., would be provided more frequently by electronic revisions with well-documented revision dates. The IERS Conventions Center invites suggestions of any type concerning these plans specifically in the following areas: 2.1 Preparation * Suggestions for procedures to gather new and updated information, to evaluate proposals for changes and to validate accuracy and consistency of models * Frequency of updates 2.2 Content * Items missing or incorrectly described in Conventions (2003) * Software routines * Technique specific constants and models 2.3 Availability * Value of paper edition in the future * Web site changes * Methods of updating web version (continuous or discrete, e.g. once a year) * Methods to record changes and past versions of text and software * New means of disseminating information such as FAQs, newsgroup, LISTSERV. 3. Interactions between Conventions Center & other IERS components / Technique services To provide further improvements in the operational procedures the Center also invites your comments and suggestions on the following: 3.1 Special Advisory Board The Conventions Center has envisioned that an Advisory Board could be set up to provide overview and guidance. * Would such a board be useful? * Suggestions for how to form such a board * Should it be permanent or temporary? 3.2 Formal acceptance * Should the Conventions be submitted to a formal acceptance process? * Who should be the approving authority and under what conditions? 3.3 Routine interactions * How best to enhance routine interactions with other IERS components and the Technique Centers? * What about other groups outside IERS?

Daylight saving goes into effect at 3:00am instead of 2:00am. Below I have attached simple test case. This is the output of the test I ran on both Mac(10.2.8) and PalmSim bash-2.05a$ TZ="Europe/Paris" ./a.out when = 0x3f9b0e44 is_dst = 1 zone = CEST Sun Oct 26 01:59:00 2003 when = 0x3f9b0e80 is_dst = 1 zone = CEST Sun Oct 26 02:00:00 2003 when = 0x3f9b11c8 is_dst = 1 zone = CEST Sun Oct 26 02:14:00 2003 when = 0x3f9b2014 is_dst = 0 zone = CET Sun Oct 26 02:15:00 2003 You will notice that the difference between 02:14:00 and 02:15:00 is 3660 which is 61 minutes. If you set the device to 2:14 and wait 46 minutes it will change the time back to 02:00. There should be no difference in setting the time to 02:00, 02:14, or 02:15 since anytime after 02:00 should fall outside of Daylight Saving Time on this date. Thanks, --jason
