Just as we start to feel spring is coming the Chilean Earthquake shifts the Earth's Axis and now our days are shorter.

Can't say I've noticed the results myself:

"If the planet's axis did shift by 8cm during the quake, days would have shortened by 1.26 microseconds. A microsecond is one-millionth of a second."

The powerful earthquake that killed hundreds of people in Chile on Saturday probably shifted the Earth's axis and made days slightly shorter, a Nasa scientist has said.
Richard Gross, a research scientist at Nasa's Jet Propulsion Laboratory in California, calculated how much the axis may have changed in position following the the disaster.
Earth days are 24 hours long because that is the amount of time it takes the planet to make one full rotation on its axis, so shifting the axis would affect rotation.

The quake shifted the Earth's axis by even more than the 9.1-magnitude tremor off Indonesia that started the deadly tsunami in Asia in 2004, according to Mr Gross.
This was partly because the fault line responsible for the quake in Chile "dips into Earth at a slightly steeper angle than does the fault responsible for the 2004 Sumatran earthquake", he said.
The different angle made Saturday's tremor more effective at moving Earth's mass vertically and shifting the planet's axis, Mr Gross continued.
The 2004 quake in Asia, which killed hundreds of thousands of people, caused the Earth to move by around 7cm.
It chopped an estimated 6.8 microseconds off the length of a day, Nasa said.

I didn't think it was fair to keep you in the dark!

Am having to switch on my lamps earlier too - very very noticeable:-D

OMG, soon our days will be 0 seconds long, arghhhhhh.

What do they mean by axis? As in our position relative to the sun, or the angle at which the earth is sitting?

Either way, I'd think too many changes that way could bring some very bad news - environmentally as opposed to losing a microsecond.

That's gonna cut the number of times we have sex down a bit!

Hmmm.... have I mentioned Jenny before?

oh God, i'm getting compo from the electric board 'cos it's on a timer.

That other quake might have shifted it back

It doesnt say in what direction quakes have shifted the axis !!!

If we can get Vanessa Feltz to just jump up and down a few times on the exact opposite side of the Earth from Chile, then we will be back to normal.
