The scheduler cannot correctly schedule once the timestamp exceeds
MAX_RELEASE_TIME as releases beyond this point may be subject to
overflow. For most systems this should still allow a great many years if
the timestamp starts from 0 at system boot.
Some systems currently start with a random initial timestamp and my
begin with a timestamp that prvents correct budgeting. This assert helps
to catch cases where scheduling becomes invalid due to the timestamp
exceeding the give bound.
