DJB (the author of libtai) disagrees with POSIX about what gettimeofday should return, and assumes that it actually returns what he wishes it returned.
It seems what should have been done was to create a modification to the kernel that allows the hardware clock to run on TAI but have gettimeofday return broken time as per POSIX, and have some other function to return TAI time. Perhaps someone's done this.
(2) We can convert TAI to UTC (and back) up to half a year in the future.
Assuming that during the half of the year: - the Haskell compiler has been updated - and released - and installed where the given software will be compiled - and the software has actually been recompiled - and the program has been restarted (if it's running as a daemon)
Of course, even if the available clock uses broken POSIX UTC time, users might still want a leap-second table to convert to TAI. -- Ashley Yakeley, Seattle WA
