Any Idea what may have caused a possible Reload of Backuppc?

Notice that according to the schedule, it was supposed to next wakeup happen at 2015-08-13 13:00:00, but the next execution with reload just happend the next day.

2015-08-13 06:00:00 Next wakeup is 2015-08-13 18:00:00
2015-08-13 18:00:00 Next wakeup is 2015-08-13 23:00:00

Below are the blackout parameters at config.pl

$Conf{BlackoutPeriods} = [
  {
    'hourEnd' => '19.5',
    'weekDays' => [
      '1',
      '2',
      '3',
      '4',
      '5'
    ],
    'hourBegin' => '7'
  }
];
