The quadratic calamity is one of the few concrete arguments given by
the proponents of dropping leap seconds (viz the GPS World article).
It continues to surface over a decade later.
I have been saying that, as a reason for changing UTC today, it is
a specious argument that should be rejected. The solution, in the
distant future when it does start to bite, will be to measure the
length of day properly - finally admit that there are more than 86400
SI seconds in it.
