Clock ident

A clock ident is a form of television ident in which a clock is displayed, reading the current time, and usually alongside the logo of that particular television station. Clock idents are typically used before news bulletins and closedown, though in the past quite commonly preceded regular programming. In the United Kingdom, it is also very much associated with schools programming.
