Twenty years ago, I tested a very large radar for the general effect of a leap second by arbitrarily causing the local clock by one second, in both directions. Radar software gyrated and settled down on the inserted leap second, and really gyrated on a deleted second. But nothing failed. This tests mostly the radar tracking software, and not leap second handling per se. The radar passed - the momentary gyration was not a problem in practice.
