Struct Clock 

pub struct Clock { /* private fields */ }

A clock that runs on another clock: its time starts at zero on the first tick of the parent after it was created, and stands still while it is paused.

The clock subscribes to its parent when it is created, whether or not anything is subscribed to it, and unsubscribes on the first tick after its play state was set to PlayState::Stop.
