Given input string: 2021-02-01T19:49:04.0513486Z

Jackson will deserialize a ZonedDateTime with the following properties:

• offset: "Z" (type ZonedOffset)
• zone: "UTC" (type ZoneRegion)

Using the standard call

DateTimeFormatter.ISO_ZONED_DATE_TIME.parse(inputString, ZonedDateTime::from);

produces:

• offset: "Z" (type ZonedOffset)
• zone: "Z" (type ZonedOffset)

This causes an issue in comparisons because id value "UTC" != id value "Z". This also produces a redundancy in the toString of the ZonedDateTime because it detects that the offset != zone.

toString for Jackson result: 2021-02-01T19:49:04.051348600Z[UTC]
toString for standard result: 2021-02-01T19:49:04.051348600Z

The latter can be consumed without extra processing and is the desired result.

Would it be possible to update the deserializer to behave like the standard call?
