问题
Client got a transaction email with flight tickets information. Documents in attachment are OK - departure is on 3rd of June Microdata sent in FlightReservation schema is OK, too (you can see it in screenshot #1)
But the client saw in panel in Gmail that the departure is on 4th of June. The arrival date is moved for one day forward, too.
P.S. about google schema https://developers.google.com/gmail/markup/reference/flight-reservation
