adjtime() changes

[Joel Sherrill]

Hi

I should point out that I am NOT trying to particularly improve the
way we adjust time. I am only

(1) making the code use timestamps not ticks

(2) moving the adjust code to the SCORE

The use of critical sections is exactly as it was before.

The preferable way to adjust TOD is in small increments per clock tick.
If someone is interested in great NTP support for RTEMS, please speak
up. Volunteering or sponsoring some work would be of benefit to
the community.
