| Admittedly, there has never been a double leap,
There never will be, that "double leap second" myth was born from a misunderstanding about "there may be two leap seconds in one year" (which meant one at the end of June, and one at the end of December, but was interpreted to mean that there might be two at the same time.)
Any code, anywhere, that is allowing for either 56, 57, 0, 1, 2 or 57, 58, 59, 60, 61, 0, 1, 2 should simply be blast from orbit.
Never say never. In 1969 CCIR Interim Working Party 7/1 produced CCIR Plenary Assembly Document VII/1008, and that allowed for multiple leap seconds. The change to remove multiple leap seconds from that document was made on 1970-02-03 in the open discussion during the 13th plenary session of 12th Plenary Assembly of the CCIR. Thus it became CCIR Recommendation 460, now evolved into the current version ITU-R TF.460-6. It is very hard to say what the ITU-R might or might not do. -- Steve Allen <sla@ucolick.org> WGS-84 (GPS) UCO/Lick Observatory--ISB 260 Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m
