But what so many miss is that what is needed to fix the problem is very small. 1) Reliably send leap second data out to the world (recently discussed here and at tz-dist) 2) Announce leap seconds a bit further in advance or on a regular schedule 3) Define a time-scale, UT-86400, that roughly follows UTC but always has 86400 "second-like" subdivisions (as per the Java time-scale) 4) Provide one or more *agreed* and *standardised* mechanisms to map UTC to UT-86400 (eg. UTC-SLS and Google smear) The fact that we don't have a name or agreed standard for the thing that most people want (outside the time-nerd community) is very sad. UT-86400 is a working name, I'm sure someone can think of a better one. The work needed isn't hard. I just wish that rather than destroying a sensible solution to keep us in line with solar days, effort would be put into defining the above.
