Just when you thought your clocks were keeping the accurate time, here comes another semi-annual round of throwing all of them off schedule.

That time-altering event, the return to Standard Time for most of the United States, puts clocks out of kilter -- or, some would say, back into kilter -- as of 2 a.m. Sunday, the first Sunday of November.

So maintain harmony with other clock-watchers, you should turn your clock back one hour before going to bed Saturday night.

The November roll-back is the flip side of Daylight Saving Time, which occurs at 2 a.m. on the second Sunday in March, when clocks are moved ahead by one hour.

Don't forget. It's a good head to make the switch the night before and spare yourself that sleepy morning question, "What time is it, really?"
