All pruning is based on the termination time of the Job concerned not the
start time of the job.
The manual was not very explicit on this, so I have made it so. Note, in a
few exceptional cases (Bacula crashes between the time the job starts and the
job terminates), the "End time" of the job will be set to the start time of
the Job. Any job that is correctly terminated by Bacula (normal, warning,
error, fail, ...) will have the End time set correctly.
