Difficult Times

If you thought telling time was easy, check out the Web site at the International Earth Rotation Service. The agency is part of the International Bureau of Weights and Measures. In addition to Eastern Daylight Time and time zones, there seems to be International Atomic Time, Universal Time and a few other measures of the elusive concept that rules our lives.

Each June 30, the agency determines whether we need to add a leap second to the year to compensate for the Earth’s rotation. As hectic as our lives are, every second counts! Check out:

Empires of Time: Calendars, Clocks and Cultures by Anthony Aveni.

Speaking of time-traveling, do you think it’ll happen in our lifetimes? If it were possible, which era would you pick?
