[tz] Portland buses remain behind the times

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: Rose J.
