by Dr. Peter Eifler July 27, 2000

July 27, 2000

I would like to write a time zone converter in Perl using your incredible time zone database. Where can I find some access code and installing instructions? Thanks for your help! Peter Eifler (from Germany)

I need help with getting data/information files for certain zones on NeXTSTEP. They are not the standard GMT+5, GMT+6, etc. files, but need it for half hour changes. I guess GMT+55 (for GMT + 5.30). These files I believe go under zoneinfo. I would really appreciate it if someone could send me step by step instructions on how to do this, or send me the data files themselves after running zic or whatever. I tried to run zic, but came up with all kinds of compiler and data errors. Thanks Firoz Vasi

tzcode standard C patch
by Torsten Duwe July 25, 2000

July 25, 2000

Dear Mr. Olson (hope "tz" is a synonym, not a list :-) , attached you find the patch we at Caldera are using for quite a while now to compile the tzcode under Linux, namely with the GNU C library, version 2 and up. I strongly believe the old code compiles on other, "tradidional" Unix-like systems (if it does so at all without changes) because of their excessive backward compatibility, that the GNU C library intentionally has not. My manuals (GNU C library and NetBSD C Library) state that strerror/perror/<errno.h> comply to ANSI X3.159-1989 (``ANSI C'') BSD 4.3, POSIX, X/OPEN . I have carefully made the changes only to the "#ifdef unix" case, but I think it is applicable in general. Thank you for your attention, Torsten Duwe --- zic.c~ Thu May 28 15:56:07 1998 +++ zic.c Mon Oct 12 17:04:02 1998 @@ -9,6 +9,7 @@ #include "tzfile.h" #ifdef unix #include "sys/stat.h" /* for umask manifest constants */ +#include <errno.h> #endif /* defined unix */ /* @@ -377,7 +378,9 @@ strerror(errnum) int errnum; { +#ifndef unix extern char * sys_errlist[]; +#endif extern int sys_nerr; return (errnum > 0 && errnum <= sys_nerr) ?
