Is there an objective-c/iPhone version of currentTimeMillis() from Java?

Question

I need to time some events in the app I\'m working on. In Java i used to be able to call currentTimeMillis() but there doesnt seem to be a version in Objective-c. Is there a way

To get very cheap very precise time, you can use gettimeofday(), which is a C Function of the BSD kernel. Please read the man page for full details, but here's an simple example:

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

long msec = t.tv_sec * 1000 + t.tv_usec / 1000;
