The Problem

The first real run with 0.15.0, werkcrappit measuring itself for 6 min 19 s, wrote no progress line, and its last line said 0:00:00.
PIT's ListenerArguments.getStartTime() is System.nanoTime(), not a wall-clock time; the listener compared it with System.currentTimeMillis().
The elapsed time came out negative, was clamped to 0, and never reached the minute that lets a line through.
The unit tests passed their own clock and start time on one scale, so they could not see it.

The Scenarios

@MC-032 and @MC-035 unchanged; now they hold in a real run.

Verified by

MutationCrapListenerTest progressCountsFromPitsNanoTimeStart: the listener's own clock against a start time 61 s back on the nanoTime scale.

The Solution

The listener's clock is milliseconds of System.nanoTime(), and PIT's start time is divided to milliseconds on the same scale.
Version 0.15.2.
