SP ensures that Fröken Ur always tells the right timeFröken Ur is the Swedish speaking clock service. SP's Time and Frequency laboratory provides the time signal, while Telia distributes it from the laboratory to callers.
Fröken Ur is a telephone service, delivering the time in spoken form to callers. Telia distributes the signal to callers, while SP's Time and Frequency laboratory in Borås produces the time information and delivers it to Telia's network.
Historically, a speaking clock time signal service has been available in Sweden since 1934, when the first machine for delivering the spoken output was installed. Any telephone subscriber could phone it to hear the time at any time of the day, which is the service that is still provided.
In 2000, the service was transferred from Telia's premises in Stockholm to SP's time and frequency laboratory in Borås, which meant that it was directly connected to the atomic clocks that maintain the country's national time scale.
