Some of you have been following the ten+ year debate about leap seconds and UTC. Since 1972 leap seconds have been used to keep civil or atomic time (UTC) close to astronomical time (e.g., UT1). Adding an extra second to the UTC timescale every couple of years allows the two to remain in close sync. There have been a total of 24 leap seconds in the past 40 years.
The next leap second is scheduled for June 30 (for those of you left of Greenwich, July 1 for those of you to the right). Anyway, a proposal to eliminate leap seconds from UTC was to be voted on at the ITU meeting in Geneva today. Some of us were on the edge of our chairs waiting for the result. As it turns out, instead of a decision, it has been postponed for a few more years. So leap seconds are safe for now. For newcomers to the list note that leap seconds, those rare one second jumps in atomic time, are a poster child for the world of precision timekeeping. You can blame them for why both leapsecond.com and time-nuts exist.
