<P> A speaking clock service was first introduced in the United Kingdom on July 24 , 1936 . The mechanism used was an array of motors , glass discs , photocells and valves which took up the floorspace of a small room . The voice was that of London telephonist Ethel Jane Cain , who had won a prize of 10 guineas in a competition to find the right voice . Cain 's voice was recorded optically onto the glass disks in a similar way to a film soundtrack . The service was obtained by dialling the letters TIM ( 846 ) on a dial telephone , and hence the service was often colloquially referred to as `` Tim '' . However this code was only used in the telephone systems of the cities of London , Birmingham , Edinburgh , Glasgow , Liverpool and Manchester . Other areas initially dialled 952 but with the introduction of subscriber trunk dialling it was changed to 80 and later 8081 as more ' recorded services ' were introduced and was standardised to 123 by the early 1990s . </P>
