Log message:
    Add code to test for unknown timezone names (following some ideas from
    Ross Reedstrom, a couple months back) and to detect timezones that are
    using leap-second timekeeping.  The unknown-zone-name test is pretty
    heuristic and ugly, but it seems better than the old behavior of just
    switching to GMT given a bad name.  Also make DecodePosixTimezone() a
    tad more robust.
