  "description": "An IANA timezone code for  the timezone offset per [BCP 175](https://www.iana.org/go/rfc6557). The offset is specified as part of a dateTime/instant (or using the tzOffset extension on a date if necessary). The timezone code may also be provided to allow for human display of the location associated with the offset. These are codes like \u0027America/New_York\u0027 or \u0027America/Los_Angeles\u0027. See [IANA Timezones](https://www.iana.org/time-zones) for the official source, and [Wikipedia](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) for information",
