proposed time zone package chages--Bangladesh, Fiji, and Samoa
by Arthur David Olson March 3, 2010

March 3, 2010

Below find proposed changes to two files in the time zone package, "asia" (changing the starting and ending time-of-day of DST in Bangladesh in 2010 and forward) and "australasia" (changing the end of DST in Fiji in 2010, adding DST in Fiji in 2010/2011, removing DST in Samoa in 2009/2010, and adding DST in Samoa in 2010/2011). If no problems are found, I plan to update the ftp version on 2010-03-08. I don't yet know whether Tunisia's abandonment of DST in 2009 was for that year only or establishes a new pattern, so I'm holding off on Tunisia changes for now. --ado ------- asia ------- *** /tmp/geta95 Wed Mar 3 17:56:45 2010 --- /tmp/getb95 Wed Mar 3 17:56:45 2010 *************** *** 1,4 **** ! # @(#)asia 8.51 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,4 ---- ! # @(#)asia 8.52 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 225,235 **** # until further notice."

No Tunisia DST in 2010 ?
by Philip.Pizzey＠sita.aero March 3, 2010

March 3, 2010

Hi there, many thanks for the continued excellent work from all the contributors to this list, much appreciated. Last year (2009) I believe that Tunisia suspended DST and the africa file was updated to reflect this change for 2009 only. The timeanddate.com entry for Tunis now states "No daylight saving time in 2010" though I have been unable to find any news reports or official announcements about this. Cheers, Phil.

March 3, 2010

The Cabinet in Fiji has decided to end DST about a month early, on 2010-03-28 at 03:00. The plan is to observe DST again, from 2010-10-24 to sometime in March 2011 (last Sunday a good guess?).

core dump from within asctime_r()
by Robert Elz Feb. 18, 2010

Feb. 18, 2010

A NetBSD user reported fsck dumping core (when attempting to correct a corrupted filesystem). That's not nice. Upon investigation, the core dump turns out to be from within asctime_r() (as called via asctime() from ctime()). The code in fsck just does p = ctime(&t); where "t" contains one of the time fields from an (already determined to be corrupted, or we wouldn't be printing) inode. ctime() is (or course) just asctime(locatime(t)) locatime() can return NULL these days, and given a nonsense time value (which is quite likely under these circumstances), probably did, but asctime() doesn't expect anything but a valus "struct tm *" and will simply dereference NULL is NULL is returned from localtime() - instant core. It would be possible to make ctime() be tm = localtime(t); if (tm == NULL) return NULL; return asctime(tm); and in theory that would be adequate, but I'm actually going to suggest moving the fix into asctime() (into asctime_r() really of course), and have asctime_r() start if (timeptr == NULL) return NULL; I think that's a safer fix. Appended is the patch I suggest, made against the tzcode2009t sources (latest I believe.) kre

proposed time zone package changes--core dump avoidance
by Arthur David Olson Feb. 14, 2010

Feb. 14, 2010

Below find proposed changes to the time zone package: * asctime.c Set errno to EINVAL and return "??? ??? ?? ??:??:?? ????\n" if asctime_r is called with a NULL struct tm pointer. (Note that asctime_r is called by ctime_r and asctime; asctime is called by ctime.) * localtime.c Set errno to EINVAL and return WRONG if time1 is called with a NULL struct tm pointer; avoid dereference if a NULL struct tm pointer is passed to timelocal, timegm, or timeoff. (Note that time1 is called by mktime, timegm, and timeoff; mktime is called by timelocal.) Barring problems, expect these changes to show up in the ftp package on 2010-02-16 (a day later than usual given a U. S. federal holiday). --ado ------- asctime.c ------- *** /tmp/geta26934 Sat Feb 6 13:23:25 2010 --- /tmp/getb26934 Sat Feb 6 13:23:25 2010 *************** *** 11,17 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)asctime.c 8.2"; #endif /* !defined NOID */ #endif /* !defined lint */ --- 11,17 ---- #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)asctime.c 8.3"; #endif /* !defined NOID */ #endif /* !defined lint */ *************** *** 91,96 **** --- 91,100 ---- char year[INT_STRLEN_MAXIMUM(int) + 2]; char result[MAX_ASCTIME_BUF_SIZE]; + if (timeptr == NULL) { + errno = EINVAL; + return "??? ??? ?? ??:??:?? ????\n"; + } if (timeptr->tm_wday < 0 || timeptr->tm_wday >= DAYSPERWEEK) wn = "???"; else wn = wday_name[timeptr->tm_wday]; ------- localtime.c ------- *** /tmp/geta26952 Sat Feb 6 13:23:25 2010 --- /tmp/getb26952 Sat Feb 6 13:23:25 2010 *************** *** 5,11 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)localtime.c 8.9"; #endif /* !defined NOID */ #endif /* !defined lint */ --- 5,11 ---- #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)localtime.c 8.10"; #endif /* !defined NOID */ #endif /* !defined lint */ *************** *** 1889,1894 **** --- 1889,1898 ---- int types[TZ_MAX_TYPES]; int okay; + if (tmp == NULL) { + errno = EINVAL; + return WRONG; + } if (tmp->tm_isdst > 1) tmp->tm_isdst = 1; t = time2(tmp, funcp, offset, &okay); *************** *** 1960,1966 **** timelocal(tmp) struct tm * const tmp; { ! tmp->tm_isdst = -1; /* in case it wasn't initialized */ return mktime(tmp); } --- 1964,1971 ---- timelocal(tmp) struct tm * const tmp; { ! if (tmp != NULL) ! tmp->tm_isdst = -1; /* in case it wasn't initialized */ return mktime(tmp); } *************** *** 1968,1974 **** timegm(tmp) struct tm * const tmp; { ! tmp->tm_isdst = 0; return time1(tmp, gmtsub, 0L); } --- 1973,1980 ---- timegm(tmp) struct tm * const tmp; { ! if (tmp != NULL) ! tmp->tm_isdst = 0; return time1(tmp, gmtsub, 0L); } *************** *** 1977,1983 **** struct tm * const tmp; const long offset; { ! tmp->tm_isdst = 0; return time1(tmp, gmtsub, offset); } --- 1983,1990 ---- struct tm * const tmp; const long offset; { ! if (tmp != NULL) ! tmp->tm_isdst = 0; return time1(tmp, gmtsub, offset); }

30 Rock
by Arthur David Olson Feb. 11, 2010

Feb. 11, 2010

In the "30 Rock" episode "Anna Howard Shaw Day" (first broadcast 2010-02-11), Jack Donaghy's date realizes that a Geneva-to-New-York business phone call received in the evening must be fake given the difference in local times. (Expect the above in the next version of tz-art.htm.) --ado

Russia may set clocks back one hour instead of going into DST

According to this article in Pravda, Russia might stop observing DST, and instead go back one hour in March to the time zones they were at until year 1930. http://english.pravda.ru/society/stories/03-02-2010/111995-time_zone-0 Best regards, Steffen Thorsen - timeanddate.com

Good day! There are two rules for Mauritius in current version of timezone/africa: Rule Mauritius 2008 max - Oct lastSun 2:00s 1:00 S Rule Mauritius 2009 max - Mar lastSun 2:00s 0 - It's wrong, because Mauritius used DST only in 2008/2009, prooflinks: http://www.timeanddate.com/news/time/mauritius-daylight-saving-time.html http://www.timeanddate.com/news/time/mauritius-dst-will-not-repeat.html So, rules should be: Rule Mauritius 2008 only - Oct lastSun 2:00s 1:00 S Rule Mauritius 2009 only - Mar lastSun 2:00s 0 - or something like that. -- Best regards, Leonid A.

I've found this government-site web page... http://dof.gob.mx/nota_detalle.php?codigo=5127480&fecha=06/01/2010 ...indicating that Ensenada is indeed to use US DST rules starting in 2010; I'll adjust the proposed time zone package changes accordingly and hope to send something out later today. --ado

I am asking for a way to give zdump a timezone, date and hour, so zdump (or other command) can give me the "isdst". Another way could be to give time zone (or Country and city), date and hour and get the UTC and "isdst". Should it be possible? Thanks in advance.
