The function localtime() uses the value of time() to fill a tm

structure with the values that represent the corresponding time,

expressed in the local timezone.

struct tm localtime(int timestamp)

Example:

struct tm 

{

   int tm_sec;      /* Seconds - [0,61] */

   int tm_min;      /* Minutes - [0,59] */

   int tm_hour;     /* Hours - [0,23] */

   int tm_mday;     /* Day of the month - [1,31] */

   int tm_mon;      /* Month in year - [0,11] */

   int tm_year;     /* Year since 1900 */

   int tm_wday;     /* Days since sunday (Weekday) - [0,6] */

   int tm_yday;     /* Days since new year (1.1.) - [0,365] */

   int tm_isdst;    /* Summertime-Flag */

};

void main ()

{

  int rawtime;

  struct tm ltime;

  rawtime = time ();

  ltime = localtime (rawtime);

  printf("localtime %d %d %d %d %d %d %d %d %d\n",ltime.tm_sec,ltime.tm_min,ltime.tm_hour,ltime.tm_mday,ltime.tm_mon,ltime.tm_year,ltime.tm_wday,ltime.tm_yday,ltime.tm_isdst);

}
