When you create an event, you choose a time zone (the default is your profile's calendar time zone).

If your invitees don't have a Vyte account and are in a different time zone of the event, they will receive the invite with the time zone of the event.
If they do have a Vyte account (they are a "Vyter"), they will receive the invite customized in their preferred time zone.
In any case, when invitees click on the confirmation of an event, if they are in a different time zone, they will see both time zones (first the event's - for example, in Paris - and then their location - for example, in London. 😊
