Time 2 hours off in MySQL

Hi All,
I’m using Hassio on a Rasp3 and MariaDB 10 on a Synology for the DB.
My question is why the time stamps in the DB (last_changed;last_updated;created) are two hours off (-2h). Both the Synology as Hassio are set to the same correct TZ.
Hassio logbook entries are correct, so when the time is retrieved from the DB hassio changes the time to the correct time. So it seems the database is using GMT (My TZ - 2 = GMT) and hassio translates this back and forth into my timezone
Is this normal or some setting; is this the same with Influxdb, and what happens with Grafana
