Every second counts

23 December 2008

There is good news for IYA2009 supporters racing to finish preparations before the new year. On 31 December, a "leap second" will be added to the world's clocks at 23 hours, 59 minutes and 59 seconds Coordinated Universal Time (UTC). This marks the 24th leap second to be added to UTC, since 1972.

These extra seconds are needed because the Earth's rotation is gradually slowing down. The happy side-effect this year is that it provides an extra moment to organise activities for IYA2009!
