I have tested two Drupal modules (Calendar and Fullcalendar) to provide calendar functionality.
Both modules seem to have problems with timezones.
Places dates in the calendar based on UTC time, but the displayed time is in the local timezone.
Places dates in the calendar based on UTC time, but the dates are also displayed in UTC time.
Views seems to be able to properly convert the date to the proper timezone when a format other than a calendar format is used.
I’ve battled timezone issues in Drupal 6, Drupal 7 and now again in Drupal 8.
is there a path forward to get a handle on timezone support or is there something that I’m doing wrong?
