Julian Hyde commented on ARROW-637:
-----------------------------------
One last quibble. You wrote
{quote}Null or length-0 string would indicate that the data has no time zone
(UTC){quote}
but I would correct it to
{quote}Null or length-0 string would indicate that the data has no time
zone{quote}
UTC is a time zone. "No time zone" is different; it means that the user needs
to bring their own interpretation.
