    Thanks for the info! While the ITU actions are difficult to
    follow by outsiders, BIPM actions are more easily visible.

    I find it most relevant that the BIPM seems to intend
    to make leap seconds a topic in the next CGPM in 2018-11.
    See

    The CGPM is similarly influential as the WRC on the
    international level, they have have ties with the OIML,
    and they are probably more metrology-oriented than the ITU.
