WE do not know what YOU want to do with the time data. As a programmer is is up to YOU to decide.

@zuoyou

For example, how do I take the hour h of a changing time in a module, which is still changing outside the module, and the formula h=h-8 is also changing along the timeline

As I explained in your other topic thread …

I want to use the variable of year, month, day, hour, minute, second and so on

shadowinfo["ShadowTime"] returns a standard Ruby Time class object.
It has instance methods to get all that you ask for.

So you need to modify these lines of code …

      @text = shadowinfo["ShadowTime"].to_s
      view.draw_text([30, 30], @text, {size: 18, color: [80, 80, 80]})

… so that you have available a direct reference to the Time object.

Also, the time text is not used outside the draw() callback method, so it should be a local text reference and not an @text instance reference.

      time = shadowinfo["ShadowTime"]
      text = time.to_s
      view.draw_text([30, 30], text, {size: 18, color: [80, 80, 80]})

Now you can call the #hour, #day, (and other methods) on the time object.

What you do with the data from the time object is your decision.
