Why not a directive rtems_clock_set (rtems_clock_time_value)?

History. Plus more people need to get the time in different formats
than need to set it in different formats.
At this point in time, I have grown to dislike the enum overloaded
style of clock_get. It makes it harder to have strict typing and
that style of routine tends to reference more support code than
any particular user needs. Thus it leads to code getting pulled in
that you won't necessarily use. So I would lean to a new small
routine. It's all up to users though.

There is this from POSIX:
const struct timespec *tp
Some of the code in posix/src is enabled all the time (e.g. sleep and
friends). Maybe it makes sense to enable this one also.
