How to get the current time in milliseconds in C Programming [duplicate]

Answer 1

If you're on a Unix-like system, use gettimeofday and convert the result from microseconds to milliseconds.

Answer 2

There is no portable way to get resolution of less than a second in standard C So best you can do is, use the POSIX function gettimeofday().

Answer 3

quick answer

#include<stdio.h>   
#include<time.h>   

int main()   
{   
    clock_t t1, t2;  
    t1 = clock();   
    int i;
    for(i = 0; i < 1000000; i++)   
    {   
        int x = 90;  
    }   

    t2 = clock();   

    float diff = ((float)(t2 - t1) / 1000000.0F ) * 1000;   
    printf("%f",diff);   

    return 0;   
}
