+=====Blog =====
-Back in the day if you needed to know the time to set your clocks you called the telephone operator and asked her for the time. Over time this became a dedicated service where an operator would site in front of a microphone reading out the time, and anyone could call in and listen to her reading the time. In time it became an automated service, with a computer reading off the time.\\

-Now in 2021, with mobile phone with network set time everywhere, this service still exists and continues to be free. \\
-In the United States it is a service provided by the [[https://www.usno.navy.mil/USNO/time/telephone-time|U.S Naval Observatory]]. USNO provides both voice announcements of the time, and services to synchronize systems over telephone modems.\\
