Last Thursday the chair of WRC-15 Special Working Group 5A3 submitted Temporary Document [68] Proposals relating to agenda item 1.14 http://www.itu.int/md/R15-WRC15-151102-TD-0068/en No further meetings of SWG 5A3 are on the calendar. The contents of that will not be available until after it is considered by a plenary session, but Saturday the CEPT ECC published a MSWord document of news from the second week of WRC-15 at http://www.cept.org/ecc/groups/ecc/cpg/page/news-from-cept-at-wrc-15,-second-week The dismaying news in that document says there will be no decision from WRC-15. That means the earliest decision is at WRC-19, so there will be leap seconds in the radio broadcast time scale at least until 2023. The news item reads The sub working group (SWG 5A3) has finished its work and has developed a draft new WRC Resolution (as part of way forward) which will be discussed at WG5A meeting. The draft Resolution sets out the framework for further work in collaboration with relevant bodies (i.e. BIPM/CIPM/CGPM etc) as ITU is not a proper body to decide the definition of UTC, and will report back in 2023 and meanwhile the ITU-R Recommendation TF 460-6 (with leap seconds) will continue to apply until 2023. The draft resolution was agreed in the sub working group however the group could not reach an agreement on proposals to modify the article 1.14 of the Radio Regulations (RR) and both options now will be will be discussed at the next WG5A level. Next step: Further discussions at the WG5A level. By 2023 the process of reconsidering leap seconds will have gone on for more than two decades. I suspect that many technical applications will find they have enough agency to choose a better time scale in the absence of an international recommendation. -- Steve Allen <[email protected]> WGS-84 (GPS) UCO/Lick Observatory--ISB 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 _______________________________________________ LEAPSECS mailing list [email protected] https://pairlist6.pair.net/mailman/listinfo/leapsecs
