Daylight Saving Time in the USA officially starts Sunday March 10, 2013 at 2:00 a.m. You will need to set your clocks forward one hour. I recommend doing this before you go to bed on Saturday night (March 9th).
On the vast majority of clocks, it is okay to set the hands forward one hour. When setting the hands, you should pause at each time the clock will strike or chime. On clocks where you set the hands directly (not having a time set knob), move the minute hand (long hand), and the hour hand will automatically follow.
Hermle Clocks (such as the ones I sell at Bill’s Clockworks): You may turn the minute hand ahead one hour, pausing each quarter hour for a chiming clock or each half hour for a striking clock.
Cuckoo Clocks: Move the minute hand ahead one hour, pausing at the hour and half hour for the clock to cuckoo.
Grandfather Clocks: Move the minute hand forward one hour, pausing at each quarter hour for the clock to chime.
Chelsea Ship’s Bell Clocks: Turn the minute hand ahead pausing at the hour and half hour for the clock to strike.
Antique American wall, mantel and shelf clocks: Move the minute hand forward one hour, pausing at the hour and half hour for the clock to strike.
French Antique Clocks: Move the minute hand forward one hour, pausing at the hour and half hour for the clock to strike.
400 Day Clocks: Move the minute hand forward one hour.
IMPORTANT: DO NOT FORCE THE MINUTE HAND. IF YOU FEEL AN OBSTRUCTION, STOP MOVING THE HAND.
IMPORTANT: DO NOT MOVE THE HOUR (SHORT) HAND – IT WILL MOVE BY ITSELF AS YOU MOVE THE MINUTE HAND.

Marine or Ship’s Chronometer: IT IS BEST TO LEAVE THE HANDS ALONE. Consult a specialist before setting a chronometer. It is best not to set the hands, just record the chronometer’s error each day.
