[tz] Portland buses remain behind the times

[Paul Eggert]

Digital readerboards on older TriMet buses in Portland won't
reflect yesterday's DST switch until April, because they're
based on an old dispatch system programmed years ago when
DST began in April.  The old system is no longer supported
and TriMet says it can't be changed.  So the clocks will be
off by an hour for a month, just like last March.  See:
