Research direction
Start by locating the C# implementation of TimestampArray and its existing timezone handling and tests. Compare the current behavior with the schema's IANA/Olson identifier examples, then verify that TimestampArray accepts identifiers such as America/New_York while retaining support for absolute offsets.

Description
Describe the enhancement requested
Summary
The format of a Timestamp may include an IANA/Olson timezone identifier, but this is not currently supported by the C# implementation in TimestampArray.
From the schema:
The time zone is a string indicating the name of a time zone, one of:
* As used in the Olson time zone database (the "tz database" or
"tzdata"), such as "America/New_York"
* An absolute time zone offset of the form +XX:XX or -XX:XX, such as +07:30
Acceptance Criteria
TimestampArraymust support IANA/Olson timezone identifiers.
