Countries consider time out on the 'leap second'
| ||||||||||||||
GENEVA (AP) -- It's high noon for the humble leap second.
After
ten years of talks, governments are headed for a showdown vote this
week on an issue that pits technological precision against nature's
whims.
The United States, France and others
are pushing for countries at a U.N. telecom meeting to abolish the leap
second, which for 40 years has kept computers in sync with the Earth
day.
Leap seconds are necessary to prevent
atomic clocks from speeding ahead of solar time. They are added at
irregular intervals, effectively stretching atomic time by a heartbeat
to make up for the irregular wobble in the Earth's rotation.
