This was one of the options presented by McCarthy around 1999 during
the early ruminations about changing UTC. It was quickly excluded
from the list of possible options, even before the Torino conference
when Arias further discussed the predictive capabilities.

It would be interesting to know why this option was excluded, but then
it would be interesting to really know why any of this is happening.
