There is an interesting PowerPoint (sigh...) at Schriever AFB's GPS
support center:

Amongst the nuggets:

 Large error makes data unusable for some applications
 Eglin radar missed the leap second in 1998
 Thousands of observations had to be discarded
 Problem was also evident at Clear

 However, host system software receiving the 23:59:60 time hack may
 not know what to do. System dependent response.

They clearly know what the problem with leap seconds is :-)

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