      Description

      support int64 UNIX timestamps with a particular resolution.

      Parquet supports timestamp millis and micros (no nanos)
      https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#datetime-types

      currently Arrow timestamps have a timezone field.
      https://github.com/apache/arrow/blob/master/format/Message.fbs#L67
      proposal to change timestamp as follows:

      • remove "timestamp" field and say it's UTC
      • add unit field (MICROS | MILLIS)
