Canada’s longest running radio program is wrong!

Rob Cruickshank noted the other day:

Naturally, I had to verify this. So I tuned to the WWV 10 MHz time signal on my amateur rig, tuned a portable radio to CBC Radio 1 FM, which broadcasts on 99.1 MHz in Toronto and recorded them together:

Noisy recording of two radios. The WWV 13:00:00 EDT tone is at roughly 9 seconds, and the NRC tone broadcast by CBC is at 19 seconds

Yup: Rob’s right – CBC is broadcasting the NRC 13:00:00 signal at 13:00:10, which for time nerds might as well be the change from Julian to the Gregorian calendar.

Waveform from Audacity showing a low tone at 9s recorded from WWV, and CBC's long beep coming at 19 seconds
Annotated waveform: the CBC long beep is ten seconds after the WWV tone

This recording was made directly from the airwaves. There should be effectively no difference between the signal broadcast times, but here we are with the “National Research Council official time signal” going out at a very wrong time indeed.
