* We include both the offset and the zone region ID, in order to handle

*
* Both the offset and zone region ID are optional when parsing.
* That's for two reasons.
*
* 1. The previous format, in Hibernate Search 5.5, used ".appendZoneId",
* which may be the offset or the zone region ID, depending on how the
* ZonedDateTime was built. Even in legacy format, we nevertheless expect
* either the zone region ID or the offset to be provided.
* 2. Depending on how a ZonedDateTime is built, there may be no zone region
* ID to output, so we must not make this part of the string mandatory. It is
* the case in particular when using ZoneOffsets to build ZonedDateTimes.
*
* See HSEARCH-2363 for more information.
