That TN is actually the number for the National Research Council (NRC) Time clock in Ottawa. If you got a call from that number then it must have been spoofed on the call display since when you call that number you get the automated system broadcasting the time (which I've used for years to get the correct time).
The NRC Eastern Standard Time guy called and asked if my refridgerator was running. I said it was, so he told me I'd better go catch it and hung up! What a joker.
