Setting clock by whistle

Every morning for years, at about 11:30, the telephone operator in a small Sierra-Nevada town received a call from a man asking the exact time.

One day the operator summed up nerve enough to ask him why the regularity.

"I'm foreman of the local sawmill," he explained. "Every day I have to blow the whistle at noon so I call you to get the exact time."

The operator giggled, "That's really funny," she said. "All this time we've been setting our clock by your whistle.
