Time Oh Give Me Time

Attention passengers: the world is slowly coming to a halt. Please put your trays in the upright position and prepare to disembark.

Seriously.

On Saturday, at exactly 7 p.m. Eastern Standard Time, one second will be added to our official record of time — Coordinated Universal Time, kept by a series of atomic clocks, housed in environmentally sealed vaults in about 80 timekeeping laboratories around the world and certified by the International Bureau of Weights and Measures in Paris.

The reason for the extra second is simple: The earth is slowing down. Since the days of Sir Isaac Newton, scientists have understood the time it takes for the earth to make a full rotation is getting longer. The gradual deceleration is caused by the gravitational pull of the moon. The same force that brings the tides is putting the brakes on the earth, albeit very slowly.

And because time is a function of planetary movement, our days are getting longer and, depending on how you look at it, time is slowing down.

So when you show up late for work on Monday, you now have a valid excuse. It isn't your fault, you're just trying to keep pace with the rest of the world.

Happy New Year.
