Note the "0000060    0004" above and the "0000060    0000" below.
The number in question is the index into the zone abbreviation characters which are "LMT\0CCT\0"; the difference is why we're seeing "CCT" (the correct behavior) on elsie and "LMT" (the worng behavior) on your system; it's also why the zgress test worked here on elsie.
