OK, good to know!

I still wasn't clear enough: It seems like the last leap second was 
added as soon as possible, i.e. at the point where the resulting offset 
would presumably just fit into the 0.7 s allowance.

Half a year or maybe even a full year later would both have been closer 
to the halfway (0.5 s) point.

Anyway, it _really_ doesn't matter today, what's done is done.
