Under VxWorks, certainly for GNAT <= 5.02, Ada.Real_Time.Time is
identical to Ada.Calendar.Time (calls clock_gettime()), and you can
alter Ada.Calendar.Time using clock_settime().
So what to do if you need to synchronize your clocks over a
distributed system? (you understand, this is the problem we had to
solve, not a request for help!)
