Check this documentation:

https://www.traccar.org/mysql/

Make sure the MySQL connector is installed with sudo apt-get install libmysql-java (that was the most recent command I could find so I'm hoping they didn't change the name for it)

For the timezone, make sure you're defining it using the tz database name (look for either the exact city or the nearest city in this list: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones)

Thanks probel solved.

@webo, you don't need to install connector.

Good to know Anton, thank you
