To define the time zone at the component level, assign an IANA time zone value to the timeZone property.
To modify time zones used for appointments, enable the editing.allowTimeZoneEditing option. Our Scheduler supports different time zones for appointment start and end dates (startDateTimeZone and endDateTimeZone appointment properties).
