[LEAPSECS] A standard for leap second smearing

NTP is designed to disseminate the SI second and a UTC timestamp. If you want a completely different timescale (e.g., UT1, or some smeared variant of UTC) it seems like this could be part of NTP, not some opaque hack below or above NTP so as to "fake out" ancient or hardcoded assumptions of NTP.

Is it really easier and wiser to propose a universal layer of kernel timekeeping hacks than to change how NTP works or how NTP is configured or how UTC is defined?
