----------------------------------
Summary: Re-use GetTimestamp in ParseToDate
Key: SPARK-32209
URL: https://issues.apache.org/jira/browse/SPARK-32209
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.1.0
Reporter: Maxim Gekk
Replace the combination of expressions SecondsToTimestamp and UnixTimestamp by
GetTimestamp in ParseToDate. This will allow to eliminate unnecessary parsing
overhead in: string -> timestamp -> long (seconds) -> timestamp -> date. After
the changes, the chain will be: string -> timestamp -> date.
