Olson database name ambiguity
by Tom Yandell March 7, 2005

March 7, 2005

Hi Apologies for cross posting this. I think that this is a problem in the data in the Olson database, but as it is a binary format it is difficult to verify this. I have come across this problem using the DateTime perl module (version 0.28) whose data is generated from the Olson database. The problem that I am experiencing is that the short name for timezones for 'Europe/London' up until 1996 were either 'GMT' or 'BST' (depending if daylight saving changes were in effect). From 1996 the name for the timezone is the rather less precise 'GMT/BST' regardless of whether daylight saving changes are in effect or not. I have attached a script that demonstrates this, and its output. Regards, Tom

Clive Feather posts some interesting historical observations about the calendar, which I suppressed from my original posting because I thought that they'd drown the readers in irrelevant detail -- a one-line summary, in my arrogant opinion, is "we don't want to go there." -- 73 de ke9tv/2, Kevin KENNY GE Corporate Research & Development kennykb(a)crd.ge.com P.

Timezone Dates for Israel [2005 and beyond]
by Ephraim Silverberg March 2, 2005

March 2, 2005

>From now on, Daylight Saving Time in the State of Israel will commence at 02:00 a.m. on the first Friday before April 2nd and will last until 02:00 a.m. on the first Sunday before the Jewish fast of Yom Kippur. The proposed law amendment can be viewed (for those who read Hebrew) at: ftp://ftp.cs.huji.ac.il/pub/tz/announcements/2005+beyond.ps Note that although the wording of the law is not final, its intent is -- a free translation of the text would read: Every year, between the last Friday of the month of March, at 02:00, and the last Sunday before the tenth of [the Hebrew month of] Tishrei [i.e. the fast of Yom Kippur], at 02:00, the time in Israel will be made one hour earlier so that it will precede Coordinated Universal Time by three hours; in a year that the first of April falls on a Friday, the time will be made earlier, in the manner mentioned, in that year, on this day at 02:00. Attached to this message are the context diffs for "tzdata2005e/asia". I have also update the ZIC entry Emacs generator at: ftp://ftp.cs.huji.ac.il/pub/tz/software/dst-israel.el although it does not use year-range short-hand notation and produces explicit dates for each year. ___________________________________________________________________________ Ephraim Silverberg, CSE System Group, Phone number: 972-2-6585521 Hebrew University, Jerusalem, Israel.

A couple of minor comments. First, the existing database uses "Apr<tab>25" and "Apr<tab><space>9" rather than "Apr<space>25" and "Apr<space><space>9". Also, it'd be a bit handier to input a range of dates rather than a single date. I used your program to write the following draft patch. I don't think this should go into the tz database just yet (Israeli politics being what they are) but I thought you might like to see the draft.

Re: proposed minor changes

Feb. 7, 2005

Ken Pizzini reviewed the proposed changes sent out last week and pointed out a change I failed to note in the summary: the setlocale calls in zic.c and zdump.c have been changed to use the LC_ALL parameter rather than the LC_MESSAGES parameter. (This based on earlier electronic mail claiming that setting only LC_MESSAGES rather than LC_ALL can lead to problems.) As suggested by Paul Eggert, the "diff -b" output appears below. --ado diff -b -c old/date.c new/date.c *** old/date.c Mon Jan 31 09:20:47 2005 --- new/date.c Mon Jan 31 14:06:49 2005 *************** *** 1,6 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)date.c 7.40"; /* ** Modified from the UCB version with the SCCS ID appearing below. */ --- 1,6 ---- #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)date.c 7.41"; /* ** Modified from the UCB version with the SCCS ID appearing below. */ *************** *** 664,670 **** cp = value; switch (dotp - cp) { default: ! wildinput(_("time"), value, _("main part is wrong length")); case 12: if (!dousg) { cent = ATOI2(cp); --- 664,671 ---- cp = value; switch (dotp - cp) { default: ! wildinput(_("time"), value, ! _("main part is wrong length")); case 12: if (!dousg) { cent = ATOI2(cp); diff -b -c old/private.h new/private.h *** old/private.h Mon Jan 31 09:19:08 2005 --- new/private.h Mon Jan 31 14:06:49 2005 *************** *** 91,103 **** #include "time.h" #include "stdlib.h" ! #if HAVE_GETTEXT - 0 #include "libintl.h" ! #endif /* HAVE_GETTEXT - 0 */ ! #if HAVE_SYS_WAIT_H - 0 #include <sys/wait.h> /* for WIFEXITED and WEXITSTATUS */ ! #endif /* HAVE_SYS_WAIT_H - 0 */ #ifndef WIFEXITED #define WIFEXITED(status) (((status) & 0xff) == 0) --- 91,103 ---- #include "time.h" #include "stdlib.h" ! #if HAVE_GETTEXT #include "libintl.h" ! #endif /* HAVE_GETTEXT */ ! #if HAVE_SYS_WAIT_H #include <sys/wait.h> /* for WIFEXITED and WEXITSTATUS */ ! #endif /* HAVE_SYS_WAIT_H */ #ifndef WIFEXITED #define WIFEXITED(status) (((status) & 0xff) == 0) *************** *** 106,116 **** #define WEXITSTATUS(status) (((status) >> 8) & 0xff) #endif /* !defined WEXITSTATUS */ ! #if HAVE_UNISTD_H - 0 #include "unistd.h" /* for F_OK and R_OK */ ! #endif /* HAVE_UNISTD_H - 0 */ ! #if !(HAVE_UNISTD_H - 0) #ifndef F_OK #define F_OK 0 #endif /* !defined F_OK */ --- 106,116 ---- #define WEXITSTATUS(status) (((status) >> 8) & 0xff) #endif /* !defined WEXITSTATUS */ ! #if HAVE_UNISTD_H #include "unistd.h" /* for F_OK and R_OK */ ! #endif /* HAVE_UNISTD_H */ ! #if !HAVE_UNISTD_H #ifndef F_OK #define F_OK 0 #endif /* !defined F_OK */ *************** *** 117,123 **** #ifndef R_OK #define R_OK 4 #endif /* !defined R_OK */ ! #endif /* !(HAVE_UNISTD_H - 0) */ /* Unlike <ctype.h>'s isdigit, this also works if c < 0 | c > UCHAR_MAX. */ #define is_digit(c) ((unsigned)(c) - '0' <= 9) --- 117,123 ---- #ifndef R_OK #define R_OK 4 #endif /* !defined R_OK */ ! #endif /* !HAVE_UNISTD_H */ /* Unlike <ctype.h>'s isdigit, this also works if c < 0 | c > UCHAR_MAX. */ #define is_digit(c) ((unsigned)(c) - '0' <= 9) *************** *** 216,222 **** void * irealloc P((void * pointer, int size)); void icfree P((char * pointer)); void ifree P((char * pointer)); ! char * scheck P((const char *string, const char *format)); /* ** Finally, some convenience items. --- 216,222 ---- void * irealloc P((void * pointer, int size)); void icfree P((char * pointer)); void ifree P((char * pointer)); ! char * scheck P((const char *string, char *format)); /* ** Finally, some convenience items. *************** *** 255,261 **** ** add one more for a minus sign if the type is signed. */ #define INT_STRLEN_MAXIMUM(type) \ !

> But I insist that there should be an entry "Asia/Beijing" first. > "Beijing Time" is represented by Shanghai, which is a unacceptable > situation. As far as we are concerned, the tzid is simply an internal tag, marking a region of the Earth that has the same timezone behavior, all the way back to the point in time where timezones started to be used instead of solar time. The name for that tzid may vary by language, and it should be the most customary form for that language (or even country). It is a bit like arguing that CN should not be the official ISO 3166 country code for China, because it is not an acronym for the Chinese name for the country. The common name is divorced from the particular combination of letters used for the code. The code is an internal tag, which should be represented with an appropriate string for whatever the user's language is. The main purpose of the code is that it be well-defined and unique. If Shanghai and Beijing ever had different timezone behavior, that would warrant having a different tzid; otherwise it doesn't. ‎Mark ----- Original Message ----- From: "Funda Wang" <fundawang(a)gmail.com> To: "Mark Davis" <mark.davis(a)jtcsv.com> Cc: "Paul Eggert" <eggert(a)CS.UCLA.EDU>; "Tz (tz(a)elsie.nci.nih.gov)" <tz(a)lecserver.nci.nih.gov> Sent: Friday, February 04, 2005 14:20 Subject: Re[2]: Corrections to timezone database > Mark> I do want to call people's attention to the CLDR project work on timezone > Mark> identifiers (http://unicode.org/cldr/) > Sounds interesting.

The others are distinguished because at some time in the past, there was some point at which they differed in time. So in this case, Asia/Shanghai differed from Asia/Harbin on 1980‑04‑30 15:29Z (8.5 vs. 8).

Funda Wang <fundawang(a)gmail.com> writes: > In fact, we do not have an official abbreviation for "The Time of > Beijing", as we do not use English :) OK, in that case we should probably stick with "CST", as it abbreviates the most commonly used English phrase for the time in China. The tz database is an English database, by and large. For example, it uses the abbreviation "CET" for Central European Time even though most residents of Central Europe use other abbrevations like "MEZ". We don't currently have the resources to localize all the abbreviations, so we stick with English ones. If and when the database is localized, we will transliterate "CST" in China to the appropriate Chinese characters (e.g., the characters for "The Time of Beijing"). > the main reason that there should be a "Beijing" is that we call > UTC+8 as "The Time of Beijing". There is longstanding precedent in the tz database for decoupling tz zone labels from informal time zone names. For example, the tz label "Europe/London" denotes local time in England, even though the people in England call their local time "Greenwich Mean Time". The case of Beijing is somewhat similar.

Funda Wang is not on the time zone mailing list; direct replies appropriately. --ado -----Original Message----- From: Funda Wang [mailto:fundawang@gmail.com] Sent: Thursday, February 03, 2005 1:14 PM To: Olson, Arthur David (NIH/NCI) Subject: Re[2]: Corrections to timezone database Olson,> The normal procedure is to use the most populous city in the time zone; thus Olson,> Shanghai rather than Beijing (and New York rather than Washington). Thanks for your clear explanation. The reason why Shanghai is the most populouse city in China is that there is no surburb around Shanghai. For other municipalities such as Beijing, Tianjin and Chongqing, there are a large area of surburb around them, while the population density of these surbub areas is far more lower than downtown. Anyway, I do think there should be a "Beijing" in timezone list. The timezone we Chinese are using is UTC+8, which is called "The Time of Beijing(TTB)" in China, rather "China Standard Time(CST)", no matter what number of population density do beijing have. Even in the western part of China, say Urumqi, they are using TTB while the actual geographic timezone it locates is UTC+7. And, you may know, someone may take it as political issue the lack of Beijing.

Proposed minor cleanups
by Olson, Arthur David (NIH/NCI) Feb. 3, 2005

Feb. 3, 2005

Below are proposed minor cleanups for the time zone code. 1. There's a change to the declarations of the "scheck" function to avoid a lint gripe. 2. Preprocessor directives of the form #if WHATEVER - 0 have been changed to the form #if WHATEVER under the assumption that we're working with ANSI standard compilers. 3. The underscored variants of definitions of constants such as SECSPERDAY have been eliminated, in line with a long-standing comment in the code. 4. And the bulk of the changes are cleanups to white space and line lengths. --ado diff -r -c old/Makefile new/Makefile *** old/Makefile Mon Jan 31 09:21:22 2005 --- new/Makefile Mon Jan 31 14:06:12 2005 *************** *** 1,4 **** ! # @(#)Makefile 7.106 # Change the line below for your time zone (after finding the zone you want in # the time zone files, or adding it to a time zone file). --- 1,4 ---- ! # @(#)Makefile 7.107 # Change the line below for your time zone (after finding the zone you want in # the time zone files, or adding it to a time zone file). *************** *** 398,404 **** tar cf - $(DOCS) $(SOURCES) $(MISC) *.[1-8].txt | gzip -9 > tzcode.tar.gz tar cf - $(DATA) | gzip -9 > tzdata.tar.gz ! typecheck: make clean for i in "long long" unsigned double; \ do \ --- 398,404 ---- tar cf - $(DOCS) $(SOURCES) $(MISC) *.[1-8].txt | gzip -9 > tzcode.tar.gz tar cf - $(DATA) | gzip -9 > tzdata.tar.gz ! typecheck: make clean for i in "long long" unsigned double; \ do \ diff -r -c old/asctime.c new/asctime.c *** old/asctime.c Mon Jan 31 09:20:46 2005 --- new/asctime.c Mon Jan 31 14:06:49 2005 *************** *** 11,17 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)asctime.c 7.30"; #endif /* !defined NOID */ #endif /* !defined lint */ --- 11,17 ---- #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)asctime.c 7.31"; #endif /* !defined NOID */ #endif /* !defined lint */ *************** *** 98,104 **** /* ** We avoid using snprintf since it's not available on all systems. */ !

Thank you all for the responses. Markus exactly explained the why. (In my application, I needed to get the local-broken-down-time format of the transition time point, but do NOT apply the STD/DST transition to it. The one mentioned in my previous email is the result that the DST transition has been applied to it, which was my fault. I figured out a way to fix it and get the right result.)

The following might help to clarify what I suspect you might got confused about: The transition times are stored in the "Seconds Since The Epoch (time_t)" time scale, which itself (like UTC) has *no* DST transitions. The effect you observed occured only *after* the application of the time_t->local-broken-down-time conversion, which you applied to convert the time_t value back into a human-consumable local-time yyyy-mm-dd hh:mm:ss display. It is only natural, that the transition time point itself is displayed using the same convention as the time point immediately afterwards. [By the way: This is for the same reason for which most digital clocks show 00:00 and not 24:00 at the midnight transition. Note that 24:00 would be valid only for the infinitesimal point in time at exactly midnight (and therefore invisible to the human eye), whereas 00:00 is a valid truncation until 00:01 is reached. Therefore, we use the backwards-looking notation 24:00 only when we refer to the end of a time interval (as in tonight 22:00-24:00), but not when we refer to the current time (as in "It is now 00:00.").] Markus -- Markus Kuhn, Computer Lab, Univ of Cambridge, GB http://www.cl.cam.ac.uk/~mgk25/ | __oo_O..O_oo__
