             Summary: Difference in results of casting float to timestamp
                 Key: SPARK-34727
                 URL: https://issues.apache.org/jira/browse/SPARK-34727
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Maxim Gekk


The code below portraits the issue:
{code:sql}
spark-sql> CREATE TEMP VIEW v1 AS SELECT 16777215.0f AS f;
spark-sql> SELECT * FROM v1;
1.6777215E7
spark-sql> SELECT CAST(f AS TIMESTAMP) FROM v1;
1970-07-14 07:20:15
spark-sql> CACHE TABLE v1;
spark-sql> SELECT * FROM v1;
1.6777215E7
spark-sql> SELECT CAST(f AS TIMESTAMP) FROM v1;
1970-07-14 07:20:14.951424
{code}

The result from the cached view *1970-07-14 07:20:14.951424* is different from un-cached view *1970-07-14 07:20:15*.
