And the report of the International Astronomical Union’s UTC Working Group describes a similar lack of consensus to what Steve describes:
Sometimes a lack of consensus implies a lack of interest. This is not such a case. Rather, informed persons have strongly disjoint positions. In such a case a framework is needed to address the concerns of all parties. For instance, the chairs’ summary of “The Colloquium on Decoupling Civil Timekeeping from Earth Rotation” discusses diverse issues and options that need to be accommodated whatever decision is taken:
Outside the two meetings organized through the American Astronautical Society (http://futureofutc.org), there have been few discussions of the engineering and societal implications of redefining Coordinated Universal Time. A lack of consensus regarding the underlying engineering issues cannot persist, whether UTC is redefined at WRC-15 or not.
A good first step would be for ITU to rather define a brand-new timescale under a different name, leaving UTC for backwards compatibility. This would certainly require a level of effort to explicitly address new engineering concerns – but that effort is required under any scenario. Consensus must be found if rock-solid timekeeping infrastructure is to be built and operated.
Consensus already exists that ITU can do whatever it wants by defining a new timescale under a new name.
