>                 URL: https://issues.apache.org/jira/browse/CALCITE-7629
>             Project: Calcite
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 1.42.0
>            Reporter: Mihai Budiu
>            Priority: Minor
>
> The parser uses SqlStdOperatorTable.DATEDIFF to represent TIMETSAMPDIFF In consequence, programs that use TIMETSAMPDIFF  will actually unparse as DATEDIFF, and will report errors about DATEDIFF, e.g.:
> SELECT(TIMESTAMP_DIFF(a, b)) FROM T
> will produce an error message like:
> Invalid number of arguments to function 'DATEDIFF'. Was expecting 3 arguments
> This is confusing for the users.
