[jira] [Created] (FLINK-24640) CEIL, FLOOR built-in functions for Timestamp should respect DST

Sergey Nuyanzin created FLINK-24640:
---------------------------------------

             Summary: CEIL, FLOOR built-in functions for Timestamp should respect DST
                 Key: FLINK-24640
                 URL: https://issues.apache.org/jira/browse/FLINK-24640
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / API
            Reporter: Sergey Nuyanzin


The problem is that if there is a date in DST time then 
{code:sql}
select floor(current_timestamp to year);
{code}
leads to result
{noformat}
2021-12-31 23:00:00.000
{noformat}
while expected is {{2022-01-01 00:00:00.000}}

same issue is with {{WEEK}}, {{QUARTER}} and {{MONTH}}
