> Remove String Manipulation from Date Parsing TimestampTZUtil
> ------------------------------------------------------------
>
> Key: HIVE-24701
> URL: https://issues.apache.org/jira/browse/HIVE-24701
> Project: Hive
> Issue Type: Improvement
> Reporter: David Mollitor
> Assignee: David Mollitor
> Priority: Major
> Labels: pull-request-available
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> This operation is pretty slow:
> {code:java}
> // Converts Date to TimestampTZ.
> public static TimestampTZ convert(Date date, ZoneId defaultTimeZone) {
> return parse(date.toString(), defaultTimeZone);
> }
> {code}
> To convert from Date to TimestampTZ, it creates a string, then parses it.
> Should be able to just look at the epoch time and do the conversion without
> all the string manipulation/parsing.
