* N. B: gettimeofday() is affected by discontinuous jumps in the system time
* (e.g., if the system administrator manually changes the system time).
* Hence this should NEVER be used for elapsed time computation.
* Instead, clock_gettime(CLOCK_MONOTONIC, ..) should be used for that (with similar shim if necessary).
