&gt; The event was literally moved to a different time UTC. I&#x27;m glad we agreed that it was rescheduled.<p>I think I see the confusion here.  If you went to a group of people and said the movie you were all going to was rescheduled from 11pm UTC to 10pm UTC because of DST you&#x27;d get a bunch of &quot;Huh?&quot; and &quot;What local time was it rescheduled to?&quot;  You&#x27;d answer it was rescheduled from 6pm  to 6pm local time.  You&#x27;d get a bunch of laughs at your &quot;geek humour&quot; while they secretly thought you were nuts.  :)<p>Social events like meetings, movies, etc. are not considered rescheduled when DST starts&#x2F;stops or the TZ rules get changed.<p>If you stored the event as UTC you&#x27;d have to alter your database when DST starts&#x2F;stops or the TZ rules changed (is your system going to compare the old and new rules automatically now?).
