             Bug #: 14606
           Summary: lost 1h in gmtime, ctime extracted date
           Product: glibc
           Version: 2.11
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
        AssignedTo: unassigned@sourceware.org
        ReportedBy: eugene.kopyshev@gmail.com
                CC: drepper.fsp@gmail.com
    Classification: Unclassified


Every year, random day in Oct, ctime resolves two different epoch times into
the same string date. tz not set, not affected, not makes an influence. For
example:

1351385541 2012-10-28 1:52:21 Sun Oct 28 01:52:21 2012
1351389141 2012-10-28 1:52:21 Sun Oct 28 01:52:21 2012

A code to get output as above:

#include<time.h>
#include<stdio.h>

int main()
{
time_t t;
struct tm *tm;

    t=1351385541;
    tm=gmtime(&t);
    printf( "%lu %d-%d-%d %d:%d:%d %s", t, tm->tm_year+1900, tm->tm_mon+1,
tm->tm_mday, tm->tm_hour, tm->tm_min, tm->tm_sec, ctime(&t) );
    t=1351389141;
    tm=gmtime(&t);
    printf( "%lu %d-%d-%d %d:%d:%d %s", t, tm->tm_year+1900, tm->tm_mon+1,
tm->tm_mday, tm->tm_hour, tm->tm_min, tm->tm_sec, ctime(&t) );
}
