Hmph ... the cfbot doesn't like that one bit.  It appears that the
"LMT" abbrev is known in my machine's system-provided tzdata tree,
but not when building our own timezone files.  I wonder if this is
exposing an existing bug (perhaps our copy of zic is too far out of
date?).  Will look into it tomorrow.
