Drop the clockid_t and swap it for a file handle like a proper Unix or
Linux interface. The rest is much the same

	fd = open /sys/class/timesource/[whatever]

	various queries you may want to do to check the name etc

	fclock_adjtime(fd, ...)

Okay, but lets extend the story:

	clock_getttime(fd, ...);

	clock_settime(fd, ...);

	timer_create(fd, ...);

Can you agree to that as well?

(We would need to ensure that 'fd' avoids the range 0 to MAX_CLOCKS).

You can't do that avoiding as you might like because the behaviour of
file handle numbering is defined by the standards. Hence the "f*"
versions of the calls (and of lots of other stuff)

Whether you add new syscalls or do the fd passing using flags and hide
the ugly bits in glibc is another question.
