> CASSANDRA-4771 added a max value of 20 years for ttl to protect against [year 2038 overflow
bug|https://en.wikipedia.org/wiki/Year_2038_problem] for {{localDeletionTime}}.
> It turns out that next year the {{localDeletionTime}} will start overflowing with the
maximum ttl of 20 years ({{System.currentTimeMillis() + ttl(20 years) > Integer.MAX_VALUE}}),
so we should remove this limitation.
