Error description

The ESP32 VROOM Ahoy-DTU should reboot at midnight if checked and timezone is set, in the settings/system config.
Instead, the timezone is always UTC +1 (default) and appears to be un-changable no matter which time zone is selected.
I am in UTC -8 so, combined with default +1 = 9 hours off. My DTU reboots at 3pm instead of midnight.
The DTU's clock display is also off by 9 hours.
The ESP time and all other times show correctly on the web page after sync with time server. However, the new timezone never gets updated in the DTU.
