[issue13309] test_time fails: time data 'LMT' does not match format '%Z'
Antoine Pitrou pit...@free.fr added the comment:
It is definitely a glibc issue. Here's a C snippet to reproduce:
#include time.h
#include stdlib.h
int main() {
time_t t;
struct tm tmp;
char str[200];
t = time(NULL);
tmp = *gmtime(t);
tmp.tm_gmtoff = 0;
tmp.tm_zone = NULL;
strftime(str, sizeof(str), %Z, tmp);
puts(str);
t = -2461446500;
localtime(t);
t = time(NULL);
tmp = *gmtime(t);
tmp.tm_gmtoff = 0;
tmp.tm_zone = NULL;
strftime(str, sizeof(str), %Z, tmp);
puts(str);
return 0;
}
Output:
CET
PMT
Calling localtime() or mktime() with a time largely in the past seems to
corrupt the glibc's internal time structures (the char *tm_zone[]).

LMT
on my Gentoo box. I'm still figuring out why...

[issue13309] test_time fails: time data 'LMT' does not match format '%Z'
Florent Xicluna florent.xicl...@gmail.com added the comment:
It seems that mktime is buggy on Gentoo.
You can try to reset its state in some way before to retry strftime:
t = time.gmtime(time.time())
s = time.strftime('%Z', t)
print(s)
time.mktime((-1, 1, 1, 0, 0, 0, -1, -1, -1))
s = time.strftime('%Z', t)
print(s)
time.mktime((1, 1, 1, 0, 0, 0, 0, 0, -1))
s = time.strftime('%Z', t)
print(s)
I guess it could output:
SAST
LMT
SAST

It outputs:
SAST
LMT
LMT
An equivalent C program to the first test:
#include time.h
#include stdlib.h
#include stdio.h
int main() {
time_t t;
struct tm *tmp;
t = time(NULL);
tmp = localtime(t);
char str[200];
strftime(str, sizeof(str), %Z, tmp);
puts(str);
struct tm tmp2;
tmp2.tm_sec = 0;
tmp2.tm_min = 0;
tmp2.tm_hour = 0;
tmp2.tm_mday = 1;
tmp2.tm_mon = 1;
tmp2.tm_year = -1;
tmp2.tm_wday = -1;
tmp2.tm_yday = -1;
tmp2.tm_isdst = -1;
mktime(tmp2);
t = time(NULL);
tmp = localtime(t);
strftime(str, sizeof(str), %Z, tmp);
puts(str);
return 0;
}
Outputs (as expected):
SAST
SAST
Perhaps it's not mktime?
