I misunderstood the timestamp, thought it was start of the phase, but it is end
of the phase.

> We print the start timestamp for each phase when logging the
> split/merge/compact/flush transaction journals and so when debugging an
> operator must do the math by hand. It would be trivial to also print the
> delta from the start timestamp of the previous phase and helpful to do so.
