Package: libc6 Version: 2.3.1-16 Severity: normal Tags: patch I ran into this problem because I assigned a Python programming time zone problem to my students <http://www.cs.ucla.edu/classes/spring03/cs131/hw/pr2.html>. Students who were running Debian testing could not do the assignment because their programs mishandled dates before 1970. Students who were running Debian stable (3.0r1) worked fine, as did students running Solaris. So this is a regression from 3.0r1.
The problem is that in libc6 2.3.1-16, mktime always returns -1 for dates that are before 1970. Here is a patch: http://savannah.gnu.org/cgi-bin/viewcvs/gnulib/gnulib/lib/mktime.c.diff?r1=1.35&r2=1.36 Here is a test program illustrating the bug: #include <time.h> #include <stdio.h> #include <stdlib.h> struct tm tm, tm0; int main (void) { time_t t; tm0.tm_sec = 0; tm0.tm_min = 0; tm0.tm_hour = 0; tm0.tm_year = 1968 - 1900; tm0.tm_mon = 1 - 1; tm0.tm_mday = 1; tm = tm0; putenv ("TZ=UTC0"); t = mktime (&tm); if (t != (time_t) -1 && tm.tm_sec == tm0.tm_sec && tm.tm_min == tm0.tm_min && tm.tm_hour == tm0.tm_hour && tm.tm_mday == tm0.tm_mday && tm.tm_mon == tm0.tm_mon && tm.tm_year == tm0.tm_year) { printf ("test succeeded\n"); return 0; } else { printf ("test failed\n"); return 1; } } -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
