Runkang He commented on CALCITE-5957:
-------------------------------------
There is another similar test case fails due to regression. The test is below:
{code:java}
f.checkScalar("cast('1241241' as TIMESTAMP)",
"1241-01-01 00:00:00", "TIMESTAMP(0) NOT NULL");
{code}
Before CALCITE-5678, the test case is passed, and after the change, it fails.
I have no idea whether '1241241' is a valid date or not. Could someone in
community give some input?

> Issue Type: Bug
> Components: core
> Affects Versions: 1.35.0
> Reporter: Runkang He
> Priority: Major
>
> DATE '1945-2-2' is a valid date. In CALCITE-5923 when we turn on the result
> check of `testCastStringToDateTime`, we find that Calcite accepted DATE
> '1945-2-2' before CALCITE-5678 but not afterwards, so this is a regression
> that we need to fix.
