Question

I am using glibs functions to convert epoch time to string as follows.
But each time it is giving me some random time.

//Convert Time in string.
GDate *date = g_date_new_julian(timestampsecs);
gchar date_string[50];
g_date_strftime(date_string, 50, (const gchar*)"%a, %I:%M %p", (const GDate*)date);
printf("Date String [%s]\n", date_string );

Why this might be happening? am i missing anything?

Thanks,
PP.

UPDATE:

As said i tried with setlocale(LC_ALL, ""); following is the output,
It is the same as i was getting before using setlocale.

You probably want to call setlocale() first, “LC_ALL” should do it. POSIX should also work, not sure about C.

g_date_strftime() is influenced by the locale setting. Its also good to store the result of g_date_strftime(), or anything else that fills a static buffer. You’ll want to know how many bytes were actually printed to the buffer.
