I do get the implication you're going for, but GPS actually ignores leap seconds for this reason. The time scale on the GPS system was fixed when it was deployed, and is 18 seconds ahead of UTC because it does not account for leap seconds.

Sometimes we design horrid systems that are harder to use than analog counterparts. Sometimes, our systems work because they required a lot of thought to go into them. AI hell is more likely to be a problem of decision trees than it is going to be anything to do with sensor disruption or time offsets.
