Just to set the standard. There is no "during" a negative leap second. A positive leap second proceeds as 23:59:59 23:59:60 <--- second added here 00:00:00 A negative leap second proceeds as 23:59:58 00:00:00 <--- whoops! second 59 is gone!!! Those systems that "smear" leap seconds over a 24 hour period will presumably just smear in the reverse direction. It would not surprise me at all if the liquid outer core keeps on its slowdown and a negative leap second would need to be scheduled sooner or later.

True,
But it's hard enough to get developers to understand the need to code for 61 seconds in a minute, and now they would need to code for 59 seconds as well.
If time systems simply skewed the time so that 60 seconds actually just took 61 seconds or 59 seconds, there would be other issues, but coders wouldn't be involved.

General press loses its *mind*:
Indeed, they seem not to know what they write about. "atomic time – the universal way time is measured on Earth – may have to change" They don't even know the difference between TAI and UTC.
