1936 #Poland
The speaking clock at the Main Post Office in Kraków, on the corner of Potocki and Wielopole Streets.

• A speaking clock is a telephone service that provides the exact current time when you call a designated number.

• It was once an essential tool before digital clocks and smartphones became common.

• The recorded voice—often of a radio announcer—would announce the time precisely, synchronized with official standards.

• Today, most speaking clocks are historical curiosities, but some still operate as reminders of early telecommunication technology.
