Scientists just voted to redefine how the world keeps time (www.scientificamerican.com)

Today an international group of scientists, diplomats, and timekeepers voted to end the leap second, which has been keeping Coordinated Universal Time (UTC) aligned with the time according to Earth’s rotation (UT1) within one second of difference.

A new system, called the “leap hour,” will allow the Earth’s rotation and official time to fall out of alignment by a full hour

Yes, you're reading this right. In a 50-100 years the difference between UTC and UT1 will grow to one minute. In about 6000 years it can be even one hour and we will have to change our schedules.
