meta hour rules don't display properly after being created when the
hour is on or after 00:00 UTC. The netlink debug looks correct for
seconds past midnight UTC, but displaying the rules looks like an
overflow or a byte order problem. I am in UTC-0400, so today, 20:00
and later exhibits the problem, while 19:00 and earlier hours are
fine.
