We don&#x27;t agree. It was not rescheduled in reality.  Your system would have said it was rescheduled to 7pm Toronto time while in reality the event would still be 6pm Tronto time.  The people using your site&#x2F;app&#x2F;whatever would be an hour late.<p>UTC is the correct was to store timestamps (things that happened) and intervals (things that need to happen x seconds&#x2F;minutes&#x2F;hours from now).<p>For future events at a specific geographical location you need to store it as local time + timezone.  Many databases have a time+timezone type.
