Description

As a metadata-only convenience, it would be useful to have an optional Olson time zone name or absolute time offset (e.g. +07:30) in the Timestamp flatbuffers type: https://github.com/apache/arrow/blob/master/format/Message.fbs#L94

Null or length-0 string would indicate that the data is time zone naive, and shall not be considered to be localized.
