great. many thanks for the quick reply. We will update the units then ... and for sure will report about the result.

sleep duration 5 s - recording duration 10s - to be honest, I believe I have done the period setting first and later on the local time setting. If that is important I will do all the steps next night again and take a not of all the steps (and screenshots) in detail then.

screenshot could be done later ... if needed. We are working with UTC+1 (means lokal time in Germany).
