À la tonalité, le temps sera...

In 1905, Paris established time over the phone, available on demand. With a microphone transmitting the sound of ticking, a member of the Observatory staff counted the minutes and seconds verbally on the same line. This system was extremely popular but time consuming. In 1933, Paris Observatory introduced an automatic speaking clock. Britain's current system was introduced in 1936.

A huge collection of my 'Factoids' can be accessed from my 'Kirt's Cogitations' table of contents.
