This commit makes `get_current_time_msec` correctly return milliseconds as opposed to microseconds. It also considers the value of `tv_sec`, so we don't lose occasionally go back in time by one second. Finally, the function is moved into `util.c` so that it can be reused elsewhere without having to consider these pitfalls.
