-------------------------------------------------------------
I guess I should use getDate() instead of getShiftDate(), but doing this I get exactly the same CCE I pasted above.

> If I replace $shift.getShiftDurationMinutesByProfileType($type, $shiftDate) with $shift.getShiftDurationMinutesByProfileType($type, $shift.getShiftDate()) the issue goes away for some reason. Sadly this does not work as a workaround in my real case.
