  Oh ? I will definitely investigate this more.

  Until we can go back to before 1977 or have computers outside the
gravity well of Earth, this is not what matters. What matters is that
we need a linear measure of time to synchronize our system clocks on,
and TAI is exactly this.

  I believe that Linux kernels crashing all over the world because of
a leap second happening makes a pretty strong case for not having the
system clock jump around. There are several solutions for that, but
none of them is simpler than just ignoring the drift at a system level
and perform conversions in userland when needed.
  I'll follow Rich's advice and try to provide a musl patch that's
minimally invasive, when I've found the right way to proceed with
