Not so. Daniel Gambis mentioned at a meeting in June 2003 the
expectation of some people at IERS then, that there probably would not
be a leap second before 2006. It seems they were wrong, but only by one

If I naively extrapolate the recent trend at


it may be quite a few years until we are going to see another one.

Earth's rotation has been accellerating almost continuously since the
invention of the leap second in 1972, as if our planet is keen to get at
least one negative leap second in before they are abolished ...
