How to measure time in milliseconds using ANSI C?
...ate on many systems.
You can use this function like this:
struct timeval tval_before, tval_after, tval_result;
gettimeofday(&tval_before, NULL);
// Some code you want to time, for example:
sleep(1);
gettimeofday(&tval_after, NULL);
timersub(&tval_after, &tval_before, &tval_...

C++ obtaining milliseconds time on Linux — clock() doesn't seem to work properly
...ts. You'll get a structure like the following:
struct timeval {
time_t tv_sec;

EDIT: As the two comments below suggest, clock_gettime(CLOCK_MONOTONIC) is a much better choice if you have it available, which should be almost everywhere these days.
