Wrong timezone in search interval

Current Situation

When creating a search or a customization for the daily plan with from=today and to=+50d the post body is

{"jobschedulerId":"scheduler_joc_cockpit","timeZone":"Europe/Berlin","dateFrom":"2017-07-19T22:00:00.000Z","dateTo":"+50d"}

The time in the from attribute is given in UTC but the timeZone is "Europe/Berlin".

Desired Behaviour

Instead of calculating the time from today the relative placeholder +0d in the date from string should be used instead of trying to calculate an UTC time. The time Europe/Berlin is ok then.
