How to get the current time in milliseconds from C in Linux?

Question

How do I get the current time on Linux in milliseconds?

Answer 1

You have to do something like this:

struct timeval  tv;
gettimeofday(&tv, NULL);

double time_in_mill = 
         (tv.tv_sec) * 1000 + (tv.tv_usec) / 1000 ; // convert tv_sec & tv_usec to millisecond
