Task history shows wrong start time

Current Situation

The task history that is shown when clicking a job in the Jobs View shows a wrong start time. It is always shown as 00:00:00 UTC (converted to the local time zone). The start time is shown correct when JobScheduler Master is not running.

The reason for this is a wrong result from the webservice call
http://host:port/jobscheduler/master/api/job/jobname?return=History&limit=10
See startedAt with the wrong start time (date is correct but time is always 00:00:00)

endedAt: '2018-12-17T12:30:29Z'
  pid: 3328
  returnCode: 0
  cause: period_single
  stepCount: 1
  startedAt: '2018-12-17T00:00:00Z'
  jobPath: /CC
  taskId: '85134'

Desired Behavior

The start time in the Jobs View should show the correct start time even when JobScheduler Master is running.

Workaround

You can see the correct start time values in the History View.
