[ntp:questions] leap second happens on...

...on June 30th/July 1st transition, so we'll have:

June 30th 23:59:59
June 30th 23:59:60
July 1st  00:00:00

The question is: does it happen at 00:00:00 UTC (so it must be shifted
ahead/behind depending on the timezone) or, by convention, it happens at
00:00:00 at the local timezone?

I am quite sure the first is the right one, but a colleague of mine
asked me the question well enough to make a doubt arise in my brain :)
