[anonymous] [bug #22017] zic can generate files which crash the linux kernel
by Paul Eggert Jan. 14, 2008

Jan. 14, 2008

<http://savannah.gnu.org/bugs/?22017> reports an interesting test case whereby zic generates data that crashes the Linux kernel. I thought I'd forward it to this mailing list so that non-Linux people can hear about it. Here's the test case. It makes the GNU C library tzfile.c fail with an assertion that numtypes==1. # /etc/timezone (auto-generated) # Daylight savings time rules # Name YrStart YrEnd Type Month,Day,At,Offset Letter Rule DAYLIGHT 2000 max - Mar lastSun 02:00 01:00 - Rule DAYLIGHT 2000 max - Oct lastSun 03:00 -01:00 - # Timezone description # NAME Offset Rule Name(/DaylightName) Zone localtime 00:00 DAYLIGHT GMT/BST

Why does localtime() call tzset() but localtime_r() not?
by Jonathan Leffler Jan. 11, 2008

Jan. 11, 2008

Actually, the subject pretty much says it all. In tzcode2007k (also in 2007h), the code in localtime.c is: struct tm * localtime(const time_t *const timep) { tzset(); return localsub(timep, 0L, &tm); } struct tm * localtime_r(const time_t *const timep, struct tm *tmp) { return localsub(timep, 0L, tmp); } I can't immediately see a justification for the asymmetry in the POSIX specification of these functions, but I could be missing something. -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

SunOS and timelocal, timegm, tzsetwall
by Jonathan Leffler Jan. 11, 2008

Jan. 11, 2008

In Makefile (for tzcode2007k), there are the comments: # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. # These functions may well disappear in future releases of the time # conversion package. For Solaris 8 (SunOS 5.8) and Solaris 10 (SunOS 5.10), neither the standard C library nor any other shared library in /lib or /usr/lib defines or references tzsetwall, timelocal or timegm -- the functions no longer exist in Solaris. I was checking on SPARC rather than Intel, but I would not expect that to matter in practice. You can, however, find references for these functions for Solaris 2.5 (aka SunOS 5.5) and Solaris 2.6 (SunOS 5.6) if you Google "site:sun.comtzsetwall" - ( 2.5: http://docs.sun.com/app/docs/doc/802-1930-03/6i5u95utq?a=view; 2.6: http://docs.sun.com/app/docs/doc/802-5747-03/6i9g1bha0?l=ko&a=view) Interestingly, there is a Solaris 8 manual page ( http://docs.sun.com/app/docs/doc/806-0627/6j9vhfn9n?l=ko&a=view) that mentions tzsetwall (but not timegm or timelocal), but I still can't find the function in any of the shared libraries on a representative Solaris 8 machine. There is a 'Solaris 8 Transition Guide' at http://docs.sun.com/app/docs/doc/805-6331/6j5vgg6bv?a=view which mentions all three - describing their replacements. -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

The Timezones are Incorrectly Encoded

http://www.php.net/manual/en/timezones.america.php For example, the wiki says "America/Los Angeles" rather than "America/Los_Angeles". Thanks! Fred

Theory file mentions CCME - CC3E is now available
by Jonathan Leffler Jan. 7, 2008

Jan. 7, 2008

In the distribution of the Olson database, the Theory file mentions "Calendrical Calculations, Millennium Edition" from 2001. There is a new edition of the book available now: Calendrical Calculations, 3rd Edn. 2008 Nachum Dershowitz, Edward M Reingold Cambridge University Press ISBN 978-0-521-88540-9 (hardback) ISBN 978-0-521-70238-6 (paperback) Web sites: http://www.cambridge.org/9780521885409 http://www.calendarists.org/ (Note: the latter web site does not mention the 3rd Edn as of 2008-01-06; I'm not clear whether it will be updated to do so. It does have an extensive set of errata for CCME on it.) -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

Shapefile for Olson time zone names
by Mark Shuttleworth Jan. 2, 2008

Jan. 2, 2008

Hi folks I'm trying to map from latitude and longitude to Olson time zone names, and haven't had any luck locating the relevant data. Does anyone know of an existing data set, in any format which I could ultimately get into PostGIS (Shapefile, or PostGIS, or anything similar), which would serve this purpose? If anyone is interested in helping to create such a data set I did find a potential starting point: this data set from BBN which is old (2002) and only maps to the UTC time offsets (+1, +2 etc): http://openmap.bbn.com/data/shape/timezone/ I would love to see such a data set becoming a standard part of the ZoneInfo repository, updated in an open fashion. If some funding would help to get that started, I'll gladly entertain proposals. Mark
