Revoking Canada’s AM/FM Radio Time Synchronization Program: Unveiling Chronological Disparity

The CBC Radio One network in Canada has been broadcasting since November 5th, 1939, or 84 years ago. The National Research Council (NRC) is responsible for time synchronization signals in the radio network. In order to synchronize time, the NRC sends an 800Hz sound for 300 milliseconds ten times before the top of the hour, followed by a one-second long tone to indicate that it is exactly noon. This signal used to be crucial in a time when clocks were not as accurate. However, with the advent of mobile phones, time synchronization has become less necessary.

The NRC still provides time synchronization signals through various channels, including web apps, shortwave radio signals at frequencies of 3.33kHz, 7.85kHz, and 14.67kHz, phone services, and most importantly, the NTP time servers time.nrc.ca and time.chu.nrc.ca at stratum-2 level.

TLDR: CBC Radio One in Canada has been broadcasting for 84 years, with the National Research Council responsible for time synchronization signals. While important in the past, time synchronization has become less necessary with the rise of mobile phones. The NRC still offers time synchronization through various channels, including web apps, radio signals, and NTP servers.
