Time::HiRes

Actual time resolution to that accuracy is chancy on most platforms. As recommended, Time::HiRes is a good bet, but most platforms will not guarantee any absolute time better than the schedulers time slice, or jiffy. If you need better, check around for 'real time' kernels.

you could use Inline::C. I'm not really a C programmer, but something like this should print the result of that C call.

print currentTimeMillis();

use Inline C => <<'END_OF_C_CODE';
#include <sys/time.h>

long currentTimeMillis() {
        long t;
        struct timeval tv;
        gettimeofday(&tv, 0);
        t = tv.tv_usec;
        return t;
}
