localtime() converts to local timing by returning a pointer to the broken down time using the "tm" structure. Time and date can be got by calling the "time()" function. The formatted output string returned is stored in a static character array. This array is overwritten by converting when the function is called.

    struct lconv *localeconv(void);

   #include <stdio.h>
   #include <time.h>
   int main ()
     {
        time_t  t ;
        struct tm  *ptr;
        time ( &t );
        ptr = localtime ( &t );
        printf ( "Current local time :: %s", asctime (ptr) );
        return 0;
     }

   Current local time:: Tue Mar 09 10:13:21 2010

In the above example "localtime()" is used to get local date and using the "asctime()" the current timing is displayed.
