It would be interesting if there were some data format (such as Vector2) specialized for time.
Don't really understand what you want. Do you want the function that shows the current time? OS.get_time() does that.
I also do not understand the question, could you give some example of what you want to do?
I want a custom time. Something similar to OS.get_time, but that I could customize.
Use a dictionary with a setget. Put hours, minutes and seconds into it.
