That's the problem with leap seconds in a nutshell, btw.

Nobody but extreme time geeks thinks about them. Nobody thinks they are important. Nobody thinks that they matter. Lots of people have a "well, it's just a second, things will mostly self correct if I screw it up, so why bother." It hasn't been until the last decade that computers have been connected enough for it to start to matter and all the "it doesn't matter to me, so screw everybody else" attitude is getting in the way.

This standard is but one example of that.

The marketplace is voting with their feet that this standard is lame and not worth doing right. Makes it kinda hard for people that want to do them right.
