I remember that! You used to be able to dial in and get the temperature and time. I would set my Timex with that and figure out what I needed to wear outside.
They also had dial-in weather, for those pre-internet, pre Weather Channel times, when the only other way to get the weather was wait for the 6 o'clock or 11 o'clock local newscasts, with some meteorologist named Barry or Dickie. (Women didn't get hired to do the TV weather back then.)
So they set up a phone number where you could dial in for the latest weather report. But all you really got was a canned forecast that was at least several hours old.
You can still get the time (at least Eastern Time) by calling the U.S. Naval Observatory: 202-762-1401
