Function localtime () in C

The function localtime () converts the calendar time, i.e., the output of function time (), into a broken-down time expressed as local time, and returns the pointer to broken-down time. If the conversion into local time fails, the function returns NULL pointer. The prototype of the function is written in the following manner:

struct tm* localtime(const time_t *Time);

where the pointer Time is the output of function time (),such that

time_t time( time_t *Time);

Illustrates the application of function localtime

#include <stdio.h> 
 #include <time.h> 
 main() 
 { 
   time_t justnow; 
   struct tm *Time; 
   time (&justnow); II address of justnow 
   Time= localtime(&justnow); 
    /* Convert the calender time to local time and return a pointer to the struct tm */ 
   printf("%s", asctime(Time)); 
    /* asctime() converts the broken down time into a string of the form given in the output.*/ 
 }
