FW: tz interface problems
by Olson, Arthur David May 23, 1998

May 23, 1998

---------- From: D. J. Bernstein[SMTP:djb@cr.yp.to] Sent: Monday, May 18, 1998 3:32 AM To: arthur_david_olson(a)nih.gov; djb(a)cr.yp.to Subject: tz interface problems 1. Check out the dates produced by sendmail on one host: Mon, 18 May 1998 16:36:37 +0930 Mon, 18 May 1998 16:36:38 +0930 Mon, 18 May 1998 16:36:39 +0929 Mon, 18 May 1998 16:36:40 +0929 The problem, of course, is that sendmail is figuring out the offset by comparing the hours and minutes shown by localtime() and gmtime(). Mailers don't care about time zone names; they want the UTC offset. Do you have a routine that, given a time, returns the offset? (1-second offsets can't be expressed in mail, but that's a separate problem.) 2. I'm sure you're aware that BSD and Linux now include your routines. Unfortunately, they don't make it easy for typical users to regenerate the time-zone files. Users could download new files, but that's a megabyte of data. The practical effect is that many systems slipped by a second in 1997, and will probably slip by another second at the end of 1998. How difficult would it be for you to get leap-second data from another file? I've been working on the Y2038 problem, and I've put together an /etc/leapsecs.dat format for recording leap seconds. ---Dan

Update of the CIA World Factbook : no more TZ map
by Antoine Leca May 19, 1998

May 19, 1998

Hi all, While browsing the CIA World factbook, I noticed that they have upgraded to 1997 version, which is very nice IMHO. <http://www.odci.gov/cia/publications/factbook/index.html> However, from our point point of view, this is not *that* nice, because they removed completely (unless I missed something) the TZ map of the world (and TZ informations about the countries as well, except a note about Kiribati moving the intl' date line). So the file www.htm should be updated to remove completely the present links. I do not know if we should keep the reference to this work. Note there is another reference to this map in the `asia' file (about Mongolia), which should be removed too. Antoine

updated strftime checking patch for gcc-2.8.1
by Olson, Arthur David April 2, 1998

April 2, 1998

Below find an updated strftime-checking patch for the c-common.c distributed with gcc-2.8.1 The patch arranges for gcc to do the same sort of checking of strftime formats as it does of printf and scanf formats. The patch also warns about formats that will (or that might in some locale) produce only the low-order two digits of a year, since such formats may cause Y2K challenges. The goal here was to minimize changes to c-common.c, so in some cases the coding is strained. Please forgive. If anyone has ideas for improvements before this goes off to the GNU folks, I'd love to hear from you. --ado *** 1.1/c-common.c Thu Apr 2 15:17:37 1998 --- 1/c-common.c Thu Apr 2 15:17:37 1998 *************** *** 643,648 **** --- 643,653 ---- || !strcmp (IDENTIFIER_POINTER (format_type), "__scanf__"))) is_scan = 1; + else if (TREE_CODE (format_type) == IDENTIFIER_NODE + && (!strcmp (IDENTIFIER_POINTER (format_type), "strftime") + || !strcmp (IDENTIFIER_POINTER (format_type), + "__strftime__"))) + is_scan = 2; else if (TREE_CODE (format_type) == IDENTIFIER_NODE) { error ("`%s' is an unrecognized format function type", *************** *** 954,959 **** --- 959,1006 ---- { NULL } }; + /* + ** Only format characters recognized by glibc 2.0.6's strftime (as of 1998-04-01) handled. + ** "2" is used to for formats which MUST do years as only two digits; + ** "3" is used for formats which MAY do years as only two digits (depending on locale). + ** "E" is used for formats where E modifier is acceptable + ** "O" is used for formats where O modifier is acceptable by standard + ** "o" is used for formats where O modifier is acceptable by GNU only + ** "G" is used for GNU extensions + */ + + static format_char_info time_char_table[] = { + + /* Sure Y2K troublemakers... */ + { "y", 0, NULL, NULL, NULL, NULL, NULL, NULL, "2EO-_0w" }, /* last 2 of year */ + { "D", 0, NULL, NULL, NULL, NULL, NULL, NULL, "2" }, /* %m/%d/%y--04/02/98 */ + { "g", 0, NULL, NULL, NULL, NULL, NULL, NULL, "2O-_0w" }, /* last 2 of ISO year */ + + /* Possible Y2K troublemakers... */ + { "cx", 0, NULL, NULL, NULL, NULL, NULL, NULL, "3E" }, /* locale date+time/date */ + + /* Literals, combo formats, and am/pm: no modifications, please! */ + { "%RTXnrt", 0, NULL, NULL, NULL, NULL, NULL, NULL, "" }, + { "P", 0, NULL, NULL, NULL, NULL, NULL, NULL, "G" }, + + /* Formats for one number that all agree take 'O' modifier (except "y" above) */ + { "HIMSUWdemw", 0, NULL, NULL, NULL, NULL, NULL, NULL, "-_0Ow" }, + + /* Standard formats for one number, GNU but not standard takes 'O' modifier + { "Vju", 0, NULL, NULL, NULL, NULL, NULL, NULL, "-_0Oow" }, + + /* GNU-only formats for one number */ + { "Gklsz", 0, NULL, NULL, NULL, NULL, NULL, NULL, "-_0OGw" }, + + /* Other stuff */ + { "ABZa", 0, NULL, NULL, NULL, NULL, NULL, NULL, "^#" }, + { "p", 0, NULL, NULL, NULL, NULL, NULL, NULL, "#" }, /* AM/PM--is upcase, so no ^ */ + { "bh", 0, NULL, NULL, NULL, NULL, NULL, NULL, "^" }, /* short month name */ + { "CY", 0, NULL, NULL, NULL, NULL, NULL, NULL, "-_0EOw" }, /* century/full year */ + + { NULL } + }; + typedef struct function_format_info { struct function_format_info *next; /* next structure on the list */ *************** *** 1000,1005 **** --- 1047,1053 ---- record_function_format (get_identifier ("vprintf"), NULL_TREE, 0, 1, 0); record_function_format (get_identifier ("vfprintf"), NULL_TREE, 0, 2, 0); record_function_format (get_identifier ("vsprintf"), NULL_TREE, 0, 2, 0); + record_function_format (get_identifier ("strftime"), NULL_TREE, 2, 3, 0); record_international_format (get_identifier ("gettext"), NULL_TREE, 1); record_international_format (get_identifier ("dgettext"), NULL_TREE, 2); *************** *** 1008,1015 **** /* Record information for argument format checking.

[worc0223@sable.ox.ac.uk] libc/537: Zone file for London is incorrect
by Ulrich Drepper March 30, 1998

March 30, 1998

Hi, We got today the appended bug report. The time code seems to work correctly according to the timezone data and since the reporter seems to be from the UK the data might be wrong. Any comment on this? Thanks, -- Uli ---------------. drepper at gnu.org ,-. 1325 Chesapeake Terrace Ulrich Drepper \ ,-------------------' \ Sunnyvale, CA 94089 USA Cygnus Solutions `--' drepper at cygnus.com `------------------------

Timezones for Romania
by Matei Conovici March 29, 1998

March 29, 1998

Hi! While trying to understand why some of our machines did not switch to DST, I noticed this part in the "europe" file ... # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Europe/Bucharest 1:44:24 - LMT 1891 Oct 1:44 - BMT 1931 Jul 24 # Bucharest MT 2:00 Romania EET%s 1981 Mar 29 2:00s 2:00 M-Eur EET%s # This may change to `E-Eur' soon, for EC compatibility. And I can certify that M-Eur was indeed changed to E-Eur, I believe since last october (not sure though). Anyway, today (29 Mar -> lastSun), 3:00 local time turned into 4:00 local time. This looks like it's E-Eur, and not M-Eur: Rule M-Eur 1981 max - Mar lastSun 2:00s 1:00 " DST" Rule M-Eur 1996 max - Oct lastSun 2:00s 0 - Rule E-Eur 1981 max - Mar lastSun 3:00s 1:00 " DST" Rule E-Eur 1996 max - Oct lastSun 3:00s 0 - I found the file on a solaris machine. Where can one find the most recent timezone definitions ?

Note that Mathew is not on the time zone mailing list (and note the space in the return address?); be sure to direct any replies to this message appropriately. --ado ---------- From: Mathew Englander[SMTP:"mathew "@ican.net] Sent: Friday, March 27, 1998 3:51 AM To: tz(a)elsie.nci.nih.gov Subject: lengthening days On my local TV news tonight, they said that NASA thinks El Niño has slowed dow the Earth's rotation, making days 1/10 of a second longer.

British Summer Time - completing the legislative jigsaw
by Joseph S. Myers March 26, 1998

March 26, 1998

I have located the 1922 Summer Time Order (Statutory Rules and Orders 1922 number 264), the last remaining untraced piece of UK legislation on Summer Time, in the Public Record Office (PRO: HO 45/11079/418515). This confirms the start and end of British Summer Time in 1922 to be Sunday 26 March to Sunday 8 October, both at 02:00 GMT. The file contains ten copies of the Order (one signed and bearing a seal), and one of the 1921 Order, but none of the Isle of Man order (S. R. & O. 1922 no. 290), which is as yet untraced. The papers in that file include letters instructing that copies of the Order be communicated to the Channel Islands, which suggests that Summer Time may have been used there. There are several files on Summer Time in HO 45 (Home Office Registered Papers) that I have not yet looked at; these are indexed under "Daylight Savings" with no cross-reference from "Summer Time". HO 380 (Summer Time and Calendars) contains files from 1962 to 1967. (The Order states that the termination of the War was defined as 31 August 1921 (!), which means that it was made within the powers of the War Emergency Laws (Continuance) Act.) People seeking copies of the Summer Time Orders should note that the following are not in the annual volumes: SR&O 1917 No. 362, SR&O 1921 No. 363, SR&O 1921 No. 364 - get from the Statutory Publications Office. SR&O 1922 No. 264 - get from the PRO (in HO 45/11079/418515). SR&O 1922 No. 290 - untraced. SR&O 1940 No. 172, SR&O 1944 No. 932, SR&O 1945 No. 312, SI 1948/495, SI 1949/373, SI 1950/518, SI 1951/430, SI 1951/451 - get from the British Library. -- Joseph S.

Timezone Database Online?
by rwk＠americom.com March 26, 1998

March 26, 1998

I ran across your this address as a source of up to date timezone information, world wide. Can you refer me to a URL with more information... Or one for a complete up-to-date and authoritative database of timezones, their names, offsets from GMT, and when/if they use summer hours (daylight savings time)? Can you tell me also... Are the dates "summer hours" go into effect standardized worldwide? And if not, is there any source for this information? We would like to be able to compute the current time (in any timezone) taking the possibility of "summer hours" into account. Thanks for any help, Dick Kreutzer AmeriCom Inc.
