Your friend is in the special ed class, right?

So my friend and i were sitting at lunch talking about natural disasters and he says "The days are getting longer and eventually the world will stop spinning creating  the end of time and an everlasting day on December 21st 2012."

I don't know, Is he right or wrong? correct me if he's right.
it's winter, so even that is completely wrong.

I always wondered how we even measure the shift in day length over each year. I would think the variance from Earth's orbit, the seasons, and just random wobbling would be more than enough to mask a measly two millisecond gain per year.

I guess it's probably a measurement over a fifty-year period or some similar length of time...

it's actually 2milliseconds every 100 years.

it's actually 2milliseconds every 100 years.

Whoops, I guess I lost some zeroes. AKA ALL OF THEM
But still, how do we measure that? Orbital variance probably causes a far greater shift in day length than that.
