 * Introduce ActiveSupport::TimeWithZone, for wrapping Time instances with a TimeZone. Introduce instance methods to Time for creating TimeWithZone instances, and class methods for managing a global time zone. [Geoff Buesing]
 
+>>>>>>> .r8815
 * Replace non-dst-aware TimeZone class with dst-aware class from tzinfo_timezone plugin. TimeZone#adjust and #unadjust are no longer available; tzinfo gem must now be present in order to perform time zone calculations, via #local_to_utc and #utc_to_local methods. [Geoff Buesing]
