Long before Standard Time, New England towns often had a steam whistle at one of the mills. Whistle would blast a noon, alerting all the mills to dismiss workers for their lunch break, and people who could afford clocks would then set their own clocks when they heard the blast. Mill owner would pay a worker to blow the whistle exactly at noon.
One worker in a nearby town would stop by the local clock shop to set his watch, then walk to the mill and pull the whistle chain right at noon.
When he retired, he told the new "whistle man" to follow the same procedure: set his watch by the clock shop, then blow the whistle.
New man's first day: he stops by the clock shop to set his watch ... but then wonders, how does the clock shop set its own clocks?
He asks the clock shop owner, who says "Easy - I just set all my clocks to noon when I hear the steam whistle."
