The Events Calendar Outlook Timezone Bug

There is a bug in the iCal export that keeps Outlook from calculating the correct time zone during daylight savings time.

There needs to be a forward slash before the time zone id in the zone definition :

DTSTART;TZID=/America/Chicago:20160607T140000

This can be fixed by editing wp-content/plugins/the-events-calendar/src/Tribe/iCal.php and changing lines 267 and 268 from

$item[] = ‘DTSTART;TZID=’ . $tz . ‘:’ . $tzoned->start;
$item[] = ‘DTEND;TZID=’ . $tz . ‘:’ . $tzoned->end;

To
$item[] = ‘DTSTART;TZID=/’ . $tz . ‘:’ . $tzoned->start;
$item[] = ‘DTEND;TZID=/’ . $tz . ‘:’ . $tzoned->end;
