Panel mySQL datasource time x-axis - data problem

Grafana Time Series Panel
1

I use a mySQL database with datetime entries in UTC.
The Grafana datasource is configured with Session Timezone +02:00 (Europe/Berlin).
When I select the last x hours to show a graph, the x-axis is like expected, but from the graph the oldest 2 hours are not shown.

Example copy from Grafana Query Inspector:

SELECT dt AS “time”, val FROM mytable
WHERE dt BETWEEN FROM_UNIXTIME(1648571077) AND FROM_UNIXTIME(1648581877)

This Query shows the complete dataset in an other SQL Client, but in Grafana not the complete graph, the first 2 hours are missing.

Is it possible to change the mySQL database to use UTC?
