Eufy playback timeline problem

When I select the continuous playback time from the Eufy application, the playback time shows the recording 1 hour ahead. I changed the timezone to a different location and restored it to its previous state, but the playback timeline is inaccessible for the last hour. When I select the last hour 1 hour ago, there is a watermark in the video that is 1 hour later than it should be.

please can someone help me? I live in Turkey
