Persisted data not shown in charts

I’m currently in the process of switching from version 2.4 to 3.2.
openHAB is running in a docker container and using JDBC (mariaDB) as persistence.

jdbc.persist files looks like

Strategies {    
	everyMinute : "0 * * * * ?"
	default = everyChange

Items {
   persistenzSpeichern*	: strategy = everyChange

I verified that the data is stored in the database and data is retrieved as you can see in the network tab:

However the charts do not show any data.
Also when clicking on analyze on the item, nothing is shown.

Is there a known issue with the charts and jdbc?
I found only some old bug reports which seemed not directly related to this or mostly the issues have been related to the rrd4j persistence which I do not use.

Where are the charts trying to fetch their data from? You haven’t mentioned setting “system default persistence” to steer that, which will not be jdbc by default.

If you are referring to the “System Services > Persistence” settings tab:
I set this one already to JDBC - forgot to mention that.

And I think I found the issue. Had a look in the log files and realized that the timezone of the log entries has been wrong. I added a new environment variable to my docker deployment

variable: TZ
value: Europe/Vienna

Now the log timestamps are correct and the chart is showing some data.

So looks to me like a bug in openHAB because the chart itself showed the correct time-frame on the axis and the data from the database had the correct timestamp. Only the chart has not been drawn.
