Re: Can honoring of daylight savings time be d
by Doug Gwyn Dec. 13, 1994

Dec. 13, 1994

I think you (Guy) have fairly accurately covered the issue. I agree that the POSIX rationale is confused, and wonder why they did not seek guidance from the C standards committee since we did thoroughly research and analyze this issue before settling on the specification in the C standard (which intentionally contains one or more small ambiguities to accommodate systems that cannot get time conversion precisely right for whatever reason). The intention is for struct tm to contain the "user-interface" time components and for all computations to be performed using corresponding time_t data, which in the general C standard is a magic cookie but which is supposed to be a uniformly ticking clock value in POSIX (with the number of ticks per second a system macro). Standard C provides a difftime() function simply because some systems may not have as clean an internal representation of time_t as UNIX does. The oscillators is supposed to tick uniformly (with very tiny tweaks to track an accepted time standard, but no "leaps" of any sort), and time_t should be an affine function of the number of accrued clock ticks. If POSIX has managed to require that the internal clock jump back and forth then it has a bug that should be fixed. "Leap seconds", like Daylight Saving Time, is an artifice due to people having an imperfect handle on the underlying nicely flowing physical phenomenon of time. That's the model behind the C standard and should be the one behind POSIX if it is to be a good specification.

tzcode94h.tar.gz and tzdata94h.tar.gz
by ado Dec. 10, 1994

Dec. 10, 1994

The files tzcode94h.tar.gz and tzdata94h.tar.gz are now available for anonymous ftp from the "pub" directory on elsie.nci.nih.gov (165.112.73.1). The files: * incorporate the changes to "zdump" and "date" to make changes to the "TZ" environment variable permanent; * incorporate the table changes that Paul Eggert sent in earlier this week; * include (and document) support for universal time specifications in data files--but do not (yet) include use of this feature in the data files. Think of this as "TZ Classic"--the software has been set up not to break if universal time shows up in its input, and the data has been left as is so as not to break existing implementations. What I'd like to do is get any other important functional changes rolled in to the code by the end of the year, then keep whatever version we've arrived at by then available on elsie. With that insurance in hand, the hope would be that in early 1995 the Europe data could be simplified by using the universal time support, and that (long deferred) code cleanup could be accomplished (perhaps with some removal of support for non-POSIX C compilers). Any insights folks have on these notions are welcome. Note that the Europe cleanup will require some care, since there are some places that use the "W-Eur", "M-Eur", and "E-Eur" rules but do not switch at 1:00 universal time. To get a sense of the issues involved, save the existing "europe" file as "europe-old", copy it to "europe-new", edit it to use the universal time support, unshar the attached file, then use the command sh regress europe-old europe-new and ponder the results. Also attached are the changes to "zic.c" (and "zic.8") for universal time support. --ado #! /bin/sh : To unbundle, sh this file echo file 'regress' >&2 cat >'regress' <<'End of regress' #! /bin/sh T1=,reg-$$a T2=,reg-$$b trap 'rm -f -r $T1 $T2; exit' 0 1 2 3 15 case $# in 2) ;; *) echo "$O: usage is $O filename filename" 1>&2 exit 1 ;; esac zic -d $T1 $1 zic -d $T2 $2 diff -r $T1 $T2 End of regress exit =============================================================================== SCCS/s.zic.c: 7.27 vs. 7.28 *** 7.27/zic.c Sat Dec 10 13:09:20 1994 --- 7.28/zic.c Sat Dec 10 13:09:21 1994 *************** *** 1,6 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)zic.c 7.27"; #endif /* !defined NOID */ #endif /* !defined lint */ --- 1,6 ---- #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)zic.c 7.28"; #endif /* !defined NOID */ #endif /* !defined lint */ *************** *** 25,30 **** --- 25,32 ---- long r_tod; /* time from midnight */ int r_todisstd; /* above is standard time if TRUE */ /* or wall clock time if FALSE */ + int r_todisuniv; /* above is universal time if TRUE */ + /* or local time if FALSE */ long r_stdoff; /* offset from standard time */ const char * r_abbrvar; /* variable part of abbreviation */ *************** *** 1113,1129 **** } rp->r_month = lp->l_value; rp->r_todisstd = FALSE; dp = ecpyalloc(timep); if (*dp != '\0') { ep = dp + strlen(dp) - 1; switch (lowerit(*ep)) { ! case 's': rp->r_todisstd = TRUE; *ep = '\0'; break; ! case 'w': rp->r_todisstd = FALSE; *ep = '\0'; break; } } --- 1115,1140 ---- } rp->r_month = lp->l_value; rp->r_todisstd = FALSE; + rp->r_todisuniv = FALSE; dp = ecpyalloc(timep); if (*dp != '\0') { ep = dp + strlen(dp) - 1; switch (lowerit(*ep)) { ! case 's': /* Standard */ rp->r_todisstd = TRUE; + rp->r_todisuniv = FALSE; *ep = '\0'; break; ! case 'w': /* Wall */ rp->r_todisstd = FALSE; + rp->r_todisuniv = FALSE; *ep = '\0'; + case 'g': /* Greenwich */ + case 'u': /* Universal */ + case 'z': /* Zulu */ + rp->r_todisstd = TRUE; + rp->r_todisuniv = TRUE; + *ep = '\0'; break; } } *************** *** 1421,1428 **** ** assuming the current gmtoff and ** stdoff values. */ ! untiltime = tadd(zp->z_untiltime, ! -gmtoff); if (!zp->z_untilrule.r_todisstd) untiltime = tadd(untiltime, -stdoff); --- 1432,1441 ---- ** assuming the current gmtoff and ** stdoff values. */ ! untiltime = zp->z_untiltime; ! if (!zp->z_untilrule.r_todisuniv) ! untiltime = tadd(untiltime, ! -gmtoff); if (!zp->z_untilrule.r_todisstd) untiltime = tadd(untiltime, -stdoff); *************** *** 1441,1447 **** continue; eats(zp->z_filename, zp->z_linenum, rp->r_filename, rp->r_linenum); ! offset = gmtoff; if (!rp->r_todisstd) offset = oadd(offset, stdoff); jtime = rp->r_temp; --- 1454,1460 ---- continue; eats(zp->z_filename, zp->z_linenum, rp->r_filename, rp->r_linenum); ! offset = rp->r_todisuniv ? 0 : gmtoff; if (!rp->r_todisstd) offset = oadd(offset, stdoff); jtime = rp->r_temp; =============================================================================== SCCS/s.zic.8: 7.8 vs. 7.10 *** 7.8/zic.8 Sat Dec 10 13:09:37 1994 --- 7.10/zic.8 Sat Dec 10 13:09:38 1994 *************** *** 209,222 **** .B w if the given time is local .q "wall clock" ! time or .B s if the given time is local .q standard ! time; in the absence of ! .B w or ! .BR s , wall clock time is assumed. .TP .B SAVE --- 209,226 ---- .B w if the given time is local .q "wall clock" ! time, .B s if the given time is local .q standard ! time, or ! .B u !

The `ado' time package proves such an extension is feasible. (The only slight problem I've seen in practice is with programs that assume every minute has 60 seconds.) However, POSIX seems to legislate the possibility away, and the NTP implementors seem to favour a complex system that jumps the clock. Bradley

Remember that there isn't anything magic about the EC rules in this seventh Directive. They are just the same sort of EC rules as in the first to sixth Directives. The only thing that changed was the agreement of a common end date. The UK/Eire end date in previous Directives was just as much an EC rule as any other. In particular, all EC Directives have used a changeover time of 01:00 UTC, right back to 1981. (At least, I am pretty sure they did, I don't have the text for the 1st--5th, but the UK changed from its traditional 02:00 GMT to 01:00 in 1981.) > The biggest near-term problem in this area will be countries that > currently differ from the EC rules only in that they switch at > midnight UTC instead of the new standard 01:00.

Greece should have changed in 1981, it joined in the year the first Directive took effect. I have no idea whether it actually did I'm afraid. Peter Ilieve peter(a)memex.co.uk

patches to zdump.c and date.c for Posix-compliant tzset behavior
by eggert＠twinsun.com Dec. 6, 1994

Dec. 6, 1994

date.c and zdump.c currently use the trick of temporarily setting `environ' to modify "TZ", then calling tzset(), then restoring `environ', then calling `localtime' to get the effect of the temporarily modified "TZ". But this trick doesn't work if `ctime', `localtime', `mktime', and `strftime' inspect "TZ" every time they are invoked, as required by Posix 1003.1b-1993 section 8.1.1 page 192 lines 54-56. The following patch fixes date.c and zdump.c to set `environ' permanently; this should work regardless of whether tzset has the Posix-required behavior or the old tz behavior. (I've already sent a patch to fix the old tz behavior -- I can resend this to whoever's interested.) =================================================================== RCS file: RCS/date.c,v retrieving revision 1994.6.1.2 retrieving revision 1994.6.1.3 diff -c -r1994.6.1.2 -r1994.6.1.3 *** date.c 1994/05/09 09:47:28 1994.6.1.2 --- date.c 1994/12/06 17:13:55 1994.6.1.3 *************** *** 299,312 **** static void dogmt() { ! register char ** saveenv; ! static char TZ_GMT0[] = "TZ=GMT0"; ! static char * fakeenv[] = { TZ_GMT0, NULL }; ! saveenv = environ; ! environ = fakeenv; ! tzset(); ! environ = saveenv; } #ifdef OLD_TIME --- 299,320 ---- static void dogmt() { ! static char **fakeenv; ! if (!fakeenv) { ! register int i, j; ! for (i = 0; environ[i]; i++) ! continue; ! if (!(fakeenv = (char **) malloc((i + 2) * sizeof(char *)))) { !

proposed changes to TZ tables
by eggert＠twinsun.com Dec. 6, 1994

Dec. 6, 1994

For the 1996 EC / EU daylight savings changes, we need at least four rulesets, one each for Western, Middle, and Eastern Europe (since the change is UTC, not local time), and one for GB-Eire (since they will continue to use `GMT' and `BST' instead of `WET' and `WET DST'). Perhaps the simplest thing is to use the existing ruleset names, using a comment to explain that as of 1996 the [WME]-Eur and GB-Eire rulesets use the EC rules. The biggest near-term problem in this area will be countries that currently differ from the EC rules only in that they switch at midnight UTC instead of the new standard 01:00. It will be a hassle to find exactly when they change their rules. We found out with Finland only because someone sent us a bug report. Countries in this category currently include Albania, Bulgaria, Estonia, Greece, Latvia, Lithuania, Moldova, Poland, Romania, Turkey, and Ukraine. Greece is the only country in this list that is required to change because it's in the EC, but most likely the rest will follow at some point. At the end of this message I enclose a patch addressing the above issues, along with the following: * The rules for South Australia and Victoria change, effective March. * There's a new Australia/Canberra zone, since Shanks says Canberra differed from NSW in 1981. This fixes an error in the 1981 NSW rule. * Pacific/Belau changes to Pacific/Palau (with a zone name change). (Palau is the world's newest country; we had been using an old name for it.) * The name of Kirgizstan's capital changed from Frunze to Bishkek. * The Cocos Islands are now in the correct ocean. * Norfolk Island's time zone name is now NRFT consistently. The following changes should be invisible to users. * NZ Rule lines now use standard time, to match the NZ Order in Council. * Add a story about Zurab Murvanidze, who cares about daylight savings time even more than we do. * Document that we typically use traditional English time zone abbreviations, but include the standardized Canadian French names as comments. * Add some cross-references. =================================================================== RCS file: RCS/africa,v retrieving revision 1994.4 retrieving revision 1994.4.1.1 diff -c -r1994.4 -r1994.4.1.1 *** africa 1994/02/07 14:57:48 1994.4 --- africa 1994/12/06 17:13:55 1994.4.1.1 *************** *** 53,58 **** --- 53,62 ---- # Omit `.' from abbreviations in names, e.g. prefer `St_Helena' # to `St._Helena'. # + # We typically use traditional English time zone abbreviations, + # and assume that applications translate them to other languages + # as part of the normal localization process. + # # I made up the following time zone abbreviations; corrections are welcome! # LMT Local Mean Time # -2:00 CVT Cape Verde Time (no longer used) =================================================================== RCS file: RCS/asia,v retrieving revision 1994.6 retrieving revision 1994.6.1.1 diff -c -r1994.6 -r1994.6.1.1 *** asia 1994/08/20 16:55:59 1994.6 --- asia 1994/12/06 17:13:55 1994.6.1.1 *************** *** 53,59 **** # 9:00 MLT Moluccas* # 9:30 CST Australian Central Standard Time # ! # See the `europe' file for Russia in Asia. # # See the `africa' file for Zone naming conventions. --- 53,59 ---- # 9:00 MLT Moluccas* # 9:30 CST Australian Central Standard Time # ! # See the `europe' file for Russia and Turkey in Asia. # # See the `africa' file for Zone naming conventions. *************** *** 277,282 **** --- 277,287 ---- 2:00 Cyprus EET%s # Georgia + # From Paul Eggert <eggert(a)twinsun.com> (1994-11-19): + # Today's _Economist_ (p 60) reports that Georgia moved its clocks forward + # an hour recently, due to a law proposed by Zurab Murvanidze, + # an MP who went on a hunger strike for 11 days to force discussion about it! + # Alas, we have no details. # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Tbilisi 2:59:16 - LMT 1880 2:59 - LST 1924 May 2 *************** *** 519,524 **** --- 524,534 ---- 5:00 - TSK 1957 Mar 6:00 Russia TS%s + # Kirgizstan + # Zone NAME GMTOFF RULES FORMAT [UNTIL] + Zone Asia/Bishkek 4:58:24 - LMT 1924 May 2 + 5:00 - TSK 1957 Mar + 6:00 Russia TS%s ############################################################################### *************** *** 555,571 **** ############################################################################### - # Kuwait # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Kuwait 3:11:56 - LMT 1950 3:00 - AST - - # Kyrgyzstan - # Zone NAME GMTOFF RULES FORMAT [UNTIL] - Zone Asia/Frunze 4:58:24 - LMT 1924 May 2 - 5:00 - TSK 1957 Mar - 6:00 Russia TS%s # Laos # Zone NAME GMTOFF RULES FORMAT [UNTIL] --- 565,574 ---- =================================================================== RCS file: RCS/australasia,v retrieving revision 1994.6 retrieving revision 1994.6.1.1 diff -c -r1994.6 -r1994.6.1.1 *** australasia 1994/08/20 16:56:00 1994.6 --- australasia 1994/12/06 17:13:55 1994.6.1.1 *************** *** 21,29 **** --- 21,31 ---- # 1944/1945 was just like 1943/1944; go with Shanks. # Zone NAME GMTOFF RULES FORMAT [UNTIL] + # Northern Territory Zone Australia/Darwin 8:43:20 - LMT 1895 Feb 9:30 - CST 1917 Jan 1 0:01 9:30 Aus CST + # Western Australia Zone Australia/Perth 7:43:24 - LMT 1895 Dec 8:00 - WST 1917 Jan 1 0:01 8:00 Aus WST 1974 Oct lastSun 2:00 *************** *** 33,38 **** --- 35,41 ---- 8:00 - WST 1991 Nov 17 2:00 8:00 1:00 WST 1992 Mar Sun>=1 3:00 8:00 - WST + # Queensland Zone Australia/Brisbane 10:12:08 - LMT 1895 10:00 - EST 1917 Jan 1 0:01 10:00 Aus EST 1971 Oct lastSun 2:00 *************** *** 45,50 **** --- 48,54 ---- 10:00 1:00 EST 1992 Mar Sun>=1 3:00 10:00 - EST + # South Australia # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule AS 1971 1985 - Oct lastSun 2:00 1:00 - Rule AS 1986 only - Oct 19 2:00 1:00 - *************** *** 52,59 **** Rule AS 1972 only - Feb 27 3:00 0 - Rule AS 1973 1985 - Mar Sun>=1 3:00 0 - Rule AS 1986 1989 - Mar Sun>=15 3:00 0 - !

>So it's time to-- > * add a couple of "Rule EU" lines to the Europe file This raises an issue I have meant to mention before. At present the W-Eur, M-Eur and E-Eur rules only differ in the time of the summer time changes. The EC Directive is the same for everybody, and specifies a time of 01:00 GMT. Because various EU countries are in 3 different timezones the changeover times in their local standard times differ. What we need is something like a `u' or `g' suffix to go with the current s and w, to indicate a time in UTC/GMT. Then one EU rule could suit everybody. > * document the current EU membership The original six: Belguim, France, (West) Germany, Italy, Luxembourg, the Netherlands. Plus, from 1 Jan 73: Denmark, Ireland, United Kingdom. Plus, from 1 Jan 81: Greece. Plus, from 1 Jan 86: Spain, Portugal. Plus, from 1 Jan 95: Austria, Finland, Sweden. (Norway negotiated terms for entry but in a referendum on 28 Nov 94 the people voted No by 52.2% to 47.8% on a turnout of 88.6%. This was almost the same result as Norway's previous referendum in 1972, they are the only country to have said No twice. Referendums in the other three countries voted Yes.) Next in the queue for membership are probably the Czech Republic, Hungary and Poland; further back are the Baltic States, Bulgaria, Romania, Slovakia, Slovenia, whatever else emerges from the wreckage of Yugoslavia, etc., etc. > * document current nonmembers who are using EU rules (if any) The only one I can speak for is Estonia, which uses EU dates but not at 01:00 GMT, they use midnight GMT. I don't think they know yet what they will do from 1996 onwards. > * document current members who are not using EU rules (if any) There shouldn't be any of these. A Directive has the force of law, member states are obliged to enact national law to implement it. The only contentious issue was the different end date for the UK and Ireland, and this was always allowed in the Directive. Peter Ilieve peter(a)memex.co.uk

UK Summer Time Order 1994
by Peter Ilieve Dec. 1, 1994

Dec. 1, 1994

The final piece of the legislative jigsaw for summer time in the UK for 1995--97 is now in place. The Summer Time Order 1994 (SI 1994/2798) came into force on 16 November. It restates the dates from the EC seventh Summer Time Directive which are already reflected in the tzdata files. Peter Ilieve peter(a)memex.co.uk
