At the 2015 WRC the general assembly seemed to admit that the folks pushing to abandon leap seconds had not done their homework. In the interim the news has been thin, but there are some good clues that the homework is being done.
The clearest of all these comes directly from the BIPM itself and gives a timeline of many things that have been happening and will be happening https://www.bipm.org/cc/PARTNERS/Allowed/2016_October/5-Decision-of-the-WRC-2015-on-the-leap-second.pdf Folks who are editing the wikipedia page on the leap second process may wish to review this as citable evidence of what is happening. This lays out that the BIPM watched the CCTF create a task group under the Working Group on TAI (WGTAI). The Task Group on Time Scale Definitions (TGTSD) first met 2016-09-28. Much, more, this lays out the timeline as seen from the BIPM. The TGTSD submitted a report to the CCTF meeting 2017-06-08/09. That approved a recommendation sent to the CIPM 2017-10/11 which might have approved a recommendation to be sent to CGPM 2018. The timeline continues into the future with a description about what the CGPM might be asked to do includes the words "after the revocation of Res. ITU-R TF. 460-6". The membership of TGTSD is visible in https://www.bipm.org/utils/common/pdf/DIR/DIR2016/time2016.pdf Also, in late October ITU-R WP7A met in Geneva. The title of a result from that meeting is visible as [43] Annex 02 - Working document towards preliminary draft new Report ITU-R TF.[UTC] - Content and structure of time signals to be disseminated by radiocommunication systems and various aspects of current and potential future reference time scales, including their impacts and applications in radiocommunication and WP7A also sent Liaison statement to Working Parties 4A, 4B, 4C, 5A, 5B, 5C, 5D, 6A, 6B, 6C, 7B, 7C and 7D which can be supposed as an alert that they all might want to read the working document. It is too soon for detailed clues about what just happened at CIPM and WP7A, but things are clearly moving along. -- Steve Allen <s...@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 _______________________________________________ LEAPSECS mailing list LEAPSECS@leapsecond.com https://pairlist6.pair.net/mailman/listinfo/leapsecs
