[jira] [Created] (ARROW-5967) [Java] DateUtility#timeZoneList is
not correct
Ji Liu created ARROW-5967:
-----------------------------
Summary: [Java] DateUtility#timeZoneList is not correct
Key: ARROW-5967
URL: https://issues.apache.org/jira/browse/ARROW-5967
Project: Apache Arrow
Issue Type: Improvement
Reporter: Ji Liu
Assignee: Ji Liu
Now {{timeZoneList}} in {{DateUtility}} belongs to Joda time.
Since we have replace Joda time with Java time in ARROW-2015, this should also be changed.
{{TimeStampXXTZVectors}} have a timezone member which seems not used now and its {{getObject}} returns Long(different with that in {{TimeStampXXVectors}} which returns {{LocalDateTime}}), should it return {{LocalDateTime}} with its timezone?
Is it reasonable if we do as follows:
# replace Joda {{timezoneList}} with Java {{timezoneList}} in {{DateUtility}}
# add method like {{getLocalDateTimeFromEpochMilli(long epochMillis, String timezone)}} in DateUtility
# Not sure make {{TimeStampXXTZVectors}} return {{LocalDateTime}}？
