Bug#652808: libglib2.0-0: glib fails to detect default timezone

[Marcus Comstedt]

Package: libglib2.0-0
Version: 2.30.2-4
Severity: normal

Dear Maintainer,

glib is unable to detect the correct timezone on my Debian system,
which is configured to CET using /etc/localtime ($TZ is not set).

Running the following test program:

--8<--
#include <stdio.h>
#include <time.h>
#include <glib.h>

int main()
{
  GDateTime * gdt  = g_date_time_new_now_local();
  printf("glib: %s\n", g_date_time_format(gdt, "%R %Z"));

  char buf[256];
  time_t now = time(0);
  struct tm *tm = localtime(&now);
  strftime(buf, sizeof(buf), "%R %Z", tm);
  printf("libc: %s\n", buf);
  
  return 0;
}
--8<--

produces the output

--8<--
glib: 15:17 UTC
libc: 16:17 CET
--8<--

I would have expected g_date_time_new_now_local() to also produce the
correct local time (CET).

The problem carries over to gnome_wall_clock in libgnome-desktop, and
therefore gnome-screensaver, which is where I noticed the issue.
