The CASIMO Flight Control software is a typical example: Every time
a leap second happens, the flight controllers are instructed to attain
a situation that does not require their existance around the leap second
and sit back and watch the fireworks.
Medicine production is another case: In continuous production
setups, all materials have to be traceable to with second granualirity
(FDA, EU and other regulations), which basically means that either
nothing happens over the leap second (ie: maintenance shutdown) or
everything in the factory has to cope correctly with leap seconds.
Fortunately, leap seconds happen in the middle of the night here in Denmark.

Never attribute to malice what can adequately be explained by incompetence.
