Bug ID: 17189
Summary: Incorrect result for %s in strftime
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: quae at daurnimator dot com
CC: drepper.fsp at gmail dot com
The %s specifier in strftime doesn't respect timezones.
Example:
#include <time.h>
#include <stdio.h>
int main() {
time_t t = 1234567890;
struct tm *tmp = gmtime(&t);
char output[200];
strftime(output, 200, "%s", tmp);
printf("%s\n",output);
return 0;
}
Run with a non UTC timezone. e.g. TZ=GMT+9
Output will be 1234600290 instead of expected 1234567890
Location in glibc:
http://fossies.org/dox/glibc-2.19/strftime__l_8c_source.html#l01133
This bug also exists in BSD's libc:
https://svnweb.freebsd.org/base/release/10.0.0/lib/libc/stdtime/strftime.c?view=markup#l312
It does not occur in musl:
http://git.musl-libc.org/cgit/musl/tree/src/time/strftime.c?id=ac0acd569e01735fc6052d43fdf57f3a07c93f3d#n127
