Do you also have problems if you lookup the timezone from code (like with MyTZ.setlocation("Europe/Amsterdam")?
I tried to put this line MyTZ.setlocation("Europe/Rome") in my setup() function, but I get an error:
error: 'MyTZ' was not declared in this scope
I also tried to setup TZ in the clock menu at runtime but I can't find the / character on onscreen keyboard...
Â
I'm not sure I could do something that would be more informative than the clock code from M5ez.cpp. Let's walk through:
[...]
Hope this helps, otherwise you'll have to tell me what is not working for you, or (better yet) show code that you are trying to make work.
I think I understood how the clock widget works, but I can't replicate it with my own widget code, here it is:
this is on a tab of its own named Widgets:

It should display the string Fx between WiFi and clock widgets (I'll modify that to display a string from a variable if I get it to work).
In my main tab (M5remDisplay) I put this:
ezBBand BBand; as a global variable declaration and BBand.begin(); in my setup() function.
This is a list of errors I got:

Thank you for helping me and having so much patience...
