C get time in milliseconds

#include <stdio.h>

#include <stdlib.h>

#include <time.h>

// Print the current date and time in C

intmain(void)

{

    // variables to store the date and time components

    inthours,minutes,seconds,day,month,year;

    // `time_t` is an arithmetic time type

    time_t now;

    // Obtain current time

    // `time()` returns the current time of the system as a `time_t` value

    time(&now);

    // Convert to local time format and print to stdout

    printf("Today is %s",ctime(&now));

    // localtime converts a `time_t` value to calendar time and

    // returns a pointer to a `tm` structure with its members

    // filled with the corresponding values

    structtm*local=localtime(&now);
