Well, my get_time calls same system call that GetTimer does.
The only difference is that GetTimer truncates the result to 32 bits.

So why is there a GetTimer? It has the same precision as my get_time and
the same faults. The only difference is that it truncates the result to
32 bits. We could just let GetTimer return the full 62 bits instead.
