    -- Resets the clock's date.
    --
    -- For the new layered Ada RTS::
    -- The date of delta delay entries on the time event queue are
    -- moved forward/backward by (set_clock - clock). The date
    -- of the delay until entries aren't changed. However, the delay until
    -- entries are reorderd on the queue.
    --
    -- For the old Ada RTS::
    -- The date of entries on the delay queue are moved forward/backward
    -- by (set_clock - clock). This is no problem for the delta delays (ADA
    -- delay statement). However, delays till an absolute date (delay_until
    -- subprogram) will be incorrect.
    --
    -- For the new layered Ada RTS::
    -- On self-hosts, if timer_support_arg /= NO_ADDR, then, its
    -- the address of the OS's time record. This allows, set_clock()
    -- to be atomically set with the OS's current time. For an
    -- example, see how set_time() is called in calendar_s.a.
