[jira] [Created] (SPARK-29200) Optimize `extract`/`date_part` for epoch

Maxim Gekk created SPARK-29200:
----------------------------------

             Summary: Optimize `extract`/`date_part` for epoch
                 Key: SPARK-29200
                 URL: https://issues.apache.org/jira/browse/SPARK-29200
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Maxim Gekk


The method `DateTimeUtils.getEpoch()` can be speeded up by avoiding decimal operations and converting shifted by time zone timestamp to decimal at the end. Results of `ExtractBenchmark` should be regenerated as well.
