When is the next leap second? And any word on whether or not they're still going to abolish them?

I don't see how they can do away with them. It is a fact that the time is not running exactly to the second every year. If they did away with them they would eventually have to adjust something or atomic time would be different then local time.

Four hours after you left (assuming you spent no time at your destination), and yet you were travelling back toward home at 2am Sunday morning in the spring when the country goes on "daylight savings time."\n\nIf that's the wrong answer, your informatio for answering the question was incomplete.

Hi Jerry, for me the best solution is http://www.timeanddate.com/worldclock/\nand you can even set it up for what ever clocks around the world you want. { :-)

it takes a full year for the earth to complete one lap so in a week its hardly moved. If a year was a full sweep of a clock, then its not got as far as 1 yet !!!\nIts 1/52th of the way round after a week. ( Or in foreign money 0.0192 ) \n\nSo lets hope its boots fit properly or else they'll be a proper kerfuffle round about February.\n\nChris

i was just reading about this issue the other day on a website and would you beleive that america was the first country to want to move to metric system but after a long time of not agreeing on issues it was dropped. it had been discussed on and off for nearly 60 years. nobody still knows why it never went ahead.

Heard it would be another year, 2 months, 25 days, 7 hours, 18 minutes and 54 seconds before we could do that...\n\nOh, and I can't wait to get that piece of................\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\ntechnology...did ya think i would say something else?  mwah

I'll take a simpler interpretation of the question and say one second is "calculated" to be 1/86400th of a day, where 86400 is the product of 24 hours times 60 minutes/hour times 60 seconds/minute. Problem is that the day (say from local noon to local noon by measuring the sun's highest point in the sky) is not constant throughout the year, so it was decided to use the average day looking over the whole year. \nFor very precise timings of experiments in the laboratory, one needs a very good pendulum or something else that oscillates or vibrates at a very constant frequency; then you can work back to what fraction of a day or how many seconds something takes. \nIn modern times cesium atoms provided the constant well defined measurable frequency, and scientists agreed to "define" one second as some number of these oscillations (9,192,631,770). Now when the earth decides to rotate at a different rate, scientists add leap seconds instead of redefining the second every year. \nLately the reliability of the cesium atom has been questioned, and since the speed of light (in vacuum) is defined as a fundamental "constant", the second can indeed be defined as how long it takes light to go some distance (299,792,458 meters), but that seems circular to me because I see a meter defined as how far light goes in 1/299,792,458 of a second.

Good question. At this point there is no expected date yet

On Wednesday this week, at two minutes and three seconds after 1:00, the time and date will be \n01:02:03, 04/05/06. \nThat won't ever happen again in our lifetimes.\n You may now return to your (normal?) lives.\n \n \nI want to know - who sits around and thinks of these things?

We have leap years because the length of a year is not an exact multiple of the length of a day (because there is no reason for them to match exactly).\n\nSince the remainder of the division is about 1/4, most leap years happen every four years -- arbitrarily, years that are evenly divisible by 4. 2004 was the last one.\n\nEvery hundred years, they skip a leap year on a year that is evenly divisible by 100. So there will be no leap year in 2100. However, if the year is evenly divisible by 400, there *IS* a leap year added as a final correction. So there WAS a leap year in 2000.\n\nThe last bit of error between the length of a day and the length of a year is corrected by the insertion of "leap seconds". Every few years (I'm not sure how often) the official clocks continue counting past 11:59:59 on December 31 and briefly flash 11:59:60 before they turn over to 12:00:00 on January 1.

good lord, they're being switched on on 9th November?! thats criminal! who's doing it? some has been/never going to be boyband no doubt\n\naw i'm only jealous cos i moved up north and cant do and see the lights any more :(

Andyoptic is correct.  They use (now) Zulu time (Greenich, England time zone), when they need to relate to Earth time for something.\n\nHowever, most of the time, they are using the mission clock which simply starts at zero when they first lift off.\n\nHours-Minutes-Seconds only.  No days, weeks, months...

Seven wrong answers so far.  Apply a method similar to that described by Inquirer (the 7th answer) to find all 48 times this happens every day.\n\nThe other correct answer is 'none', since my digital clock doesn't have hands.

Their headquarters are in California. I'm in NY. So I know they're 3 hours earlier than I am. Below is a link to a world time zone map that should be a big help.

Are you trying to figure out when it stops? \n\nIf so, look at your units:\n\nYou have meters per second squared, and meters per second... To get to seconds you're going to invert the meters per second squared and then multiply... \n\nYour answer is 7 seconds.
