No, that's not how leap seconds work. Do you have a reference for this idea, or did you just make it up. The signed integer TAI-UTC is a step function. The step occurs between the end of one month and the beginning of the next. Tables that encode these steps only need one entry per leap. UTC flows constantly one SI second at a time. Every second has the same billion nanoseconds. You either delete a label (23:59:59) or add a label (23:59:60) but there is no fast or slow about it. It sounds like you are confusing UTC with leap smearing, but I know you better than that. /tvb _______________________________________________ LEAPSECS mailing list LEAPSECS@leapsecond.com https://pairlist6.pair.net/mailman/listinfo/leapsecs
