Like the rest of the country, the Vineyard will shift from Standard to Daylight Saving Time on Sunday morning. “Spring forward, fall back,” as they say. The concept is that clocks should be turned back an hour. But for those who own old windup clocks, and many with battery-run mechanical clocks, it is better to turn the clock forward eleven hours. Turning a clock ahead instead of back is less punishment on the interior delicate gears.
