Where to find 6.8 microseconds?

Under the sofa?

does this mean all the worlds atomic clocks are wrong?

Also, do the seconds come off the working part of the day or the sleeping part? I want to know if i'm getting paid extra or losing out on sleep.

Thats a good point. Lets all email Mr Gross and ask him

The same amount of time has passed, the earthquake didn't change the laws of physics, so the atomic clocks are right.

What they may do is add it into the next leap second calculation.

Any time obviously comes out of your sleeping time, business can't be expected to pay the pennies it would cost to give everyone 6.8usec of extra holiday. We don't live in a communist state you know.

It took me more than 6.8 microseconds to work out I really don't care

No wonder I feel so tired

24 hours is the time taken to do 1 revolution on the earths axis, so how can shifting that axis alter the time it takes to revolve?!?! I'm confused, surely it still takes 24 hours, it's just a bit on the wonk now

It may have taken 6.8 microseconds of daylight (or darkness) from certain parts of the earth but it couldn't shorten the day(24 hours)

or could it?

If the rotational speed of the planet changes then the length of the day will change. 24 hours will still take 86400 seconds, but the time difference between mid day and mid day the next day could be shorter or longer.

Anyway to quote wikipedia :-

A sidereal day is approximately 23 hours, 56 minutes, 4.091 seconds (23.93447 hours or 0.99726957 SI days), corresponding to the time it takes for the Earth to complete one rotation relative to the vernal equinox.

As far as I understand, a chunk of crust must have moved vertically (inwards towards centre of the earth in this case) in order to have shortened the length of the day. The same effect as a spinning figure skater tucking in their arms/legs causing them to spin faster. Just saying the 'axis has shifted' doesn't seem to be all that technically correct a description.

You might as well judging by the amount of control big brother has over your life here in the UK

Hold on, leap second? Day shortened by 1.2 microseconds?

Humans defined the measurements of time, why the F are we now having to adjust our own measurements because we got it wrong? I'm going to have to take a few hundred miles off my car because they're "leap miles" and don't count because a mile is actually 1.0000000000000000000000000121 of a mile.
