[LEAPSECS] Leap smear

[Gerard Ashton]

The following post seems to emphasize personal preference over societal 
agreement about what time it is.
But if UT1 and broadcast time are allowed to part ways, one of them 
must, and will be, adopted as the
de facto legal time scale. The difference will quickly become great 
enough to matter in computer-mediated
transactions (e.g., whether one's income tax return was filed on time, 
or the ending time of an on-line auction.)
In less than a century the difference will be perceptible in 
human-to-human transactions (e.g., a student being
punished for tardiness). [The de facto adoption might or might not be 
accompanied by a de jure adoption.
In the worst case, one will be adopted for most interactions, but a few 
legal interactions will follow the other.]

Second-guessing who cares, or having an opinion on who should care is rather condescending and also irrelevant to the (quite serious) issue of reliability and trustworthiness of standards.
