How to change a time zone in linuxserver/domoticz

I have linux server / domoticz installed on QNAP ContainerStation
Everything works well.
Only the time zone is set to Europe / London, as you can change it.
I tried to login to linux, unfortunately all connections are rejected.
There is a console at QNAP. You can see domoticz logs there, but you can’t execute commands.
Maybe someone will tell me how to change this time zone.

Best regards and sorry for my english

Did you set the TZ variable to your timezone?

I just didn’t set it because I didn’t know where to do it. I thought this could be changed after installation. Now I don’t know how to do it.

You need to set the environment variables that we list on our readmes. See here on how to add those those on container station:

Thank you for quick help.
I had to upload the domoticz again.
I have saved the database so all data is current.
Time zone set to correct.
