The logging and status text for plans being deferred for rising plan delay report the wrong deferral-end time. For example:
21-Oct-2009 09:18:55.4: Plan AC_Mon is rising, with 171 min. remaining till dawn
21-Oct-2009 09:18:55.4: deferred (rising) for 111 min, until 21-Oct-2009 09:18:55 UTC
Note the "until" time is the current time!
