> Do not write original type for timezone-agnostic timestamps
> -----------------------------------------------------------

> Key: PARQUET-1487
> URL: https://issues.apache.org/jira/browse/PARQUET-1487
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-mr
> Affects Versions: 1.11.0
> Reporter: Zoltan Ivanfi
> Assignee: Nandor Kollar
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.11.0
>
>
> Historically, the TIMESTAMP_MILLIS and TIMESTAMP_MICROS original types used
> for the INT64 physical type were always UTC-normalized.
> The new TIMESTAMP logical type allows both UTC-normalized and
> timezone-agnostic timestamps and writes the legacy original types for
> compatibility reasons. However, the latter should only be written for
> UTC-normalized timestamps, because legacy readers are not prepared to handle
> timezone-agnostic timestamps correctly and the original type would just be
> misleading.
