Yeah, they do, but that doesn't mean you get it from your local
affiliate.  The time is not on a line that is normally broadcast,
like closed captions are.  It's up higher in the vertical interval.
Typically, locally generated test signals are placed there by the
time it's broadcast.

I remember some years ago that channel 5 in Boston had test
signals there but channel 9 across the border in New Hampshire
transmitted the network time code. (These are both ABC outlets.)
None of the Boston stations transmit the time code, so I dropped
the idea of building a decoder for it.
