1801: fix microsecond calculation for TimeSpec r=rtzoeller a=StephanvanSchaik

The implementation of `num_microseconds()` for `TimeSpec` returns the number of seconds not microseconds, as it divided by the wrong factor. The number of nanoseconds should be divided by 1000 to get the number of microseconds.
