Vue Scheduler - Time Zone Support
Appointments are displayed in the client time zone. The time-zone offset specified in the startDate or endDate is also taken into account (if there is any). You can force a time zone for an individual appointment via its startDateTimeZone and endDateTimeZone fields or for all appointments via its timeZone property. timeZone takes precedence over start/endDateTimeZone.
You can use the following formula to calculate an appointment's resulting time-zone offset:
`resultingOffset` = `timeZoneOffset` - `clientOffset` (or `embeddedOffset` if there is any)
where
timeZoneOffsetis the offset of the timeZone or start/endDateTimeZone.clientOffsetis the offset of the client side.embeddedOffsetis the offset specified in the start/endDate.
The calculated offset is then added to the date-time value.
For example, if the timeZone is "Europe/Berlin" (UTC offset +1), and the client is in Tokyo (UTC offset +9), the calculated offset is 1 - 9 = -8. The time of all appointments is shifted back 8 hours: the appointment that started at 2019-01-01T12:00:00 starts at 2019-01-01T04:00:00. The same applies when the time-zone offset is specified in the date-time value (2019-01-01T12:00:00+09:00), except that this offset is used instead of the client offset.
To allow users to change appointment time zones, enable the editing.allowTimeZoneEditing property.
