Hey Steve,
Remember that the recent large earthquake actually shifted the earths axis by something like 10 meters, so the calender now changes...

So you have to calculate the bi-lateral distribution of the overall retro motion of solidity dynamics to get to the underlying root value of equatic quantation and then compensate for the fluidity of "caso-normal", which leaves you with an hortmaticle resulting value leading towards future easy computation. This is the simple explanation of course, but I'm sure the govt. has the final, complete analysis posted!

I think we now say "Ciao cruel world!" :o
