+Subject: meta: fix hour decoding when timezone offset is negative
+
+Brian Davidson says:
+
+ 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.
+
+meta.c only ever worked when the delta to UTC is positive.
+We need to add in case the second counter turns negative after
+offset adjustment.
+
+Also add a test case for this.
+
+Fixes: f8f32deda31d ("meta: Introduce new conditions 'time', 'day' and 'hour'")
