  > Why do you call it "duration-time"? Because it has units of time (seconds, often) and it's done using time-stamps, as in begin-time and end-time. > It seems obvious that for an event that lasted 5.43s for example, (a "duration", better wording) that it's not counted with leap-seconds. Obvious until you try to get someone to understand why their time-stamps can't be UTC if they're going to be used for duration-time instead of wallclock-time. Obvious until you try to get a library or language implementer to understand the UTC isn't Universal.

    >Because it has units of time (seconds, often) and it's done using time-stamps, as in begin-time and end-time. If you are recording a duration you have another unit. If you use begin-time and end-time you are calculating a duration, which is different of course. If you calculate durations, then you might consider leap seconds, if they are important for your measurement. If not, then you just ignore them. I don't see a problem here. Besides, leap-seconds are known, so removing them from a calculated duration is not a problem.
