>                 Key: CALCITE-2989
>                 URL: https://issues.apache.org/jira/browse/CALCITE-2989
>             Project: Calcite
>          Issue Type: Bug
>          Components: avatica
>            Reporter: vinoyang
>            Priority: Major
>
> If we uses avatica's {{DateTimeUtils}} the dates less than 2299161 will cause an error result in Flink table/sql , test code :
> {code:java}
> testAllApis(
>   "1500-04-30 12:00:00".cast(Types.SQL_TIMESTAMP),
>   "'1500-04-30 12:00:00'.cast(SQL_TIMESTAMP)",
>   "CAST('1500-04-30 12:00:00' AS TIMESTAMP)",
>   "1500-04-30 12:00:00.0")
> {code}
> result :
> {code:java}
> Expected :1500-04-30 12:00:00.0
> Actual :1500-04-20 12:00:00.0
> {code}
> another case is here : 
> https://issues.apache.org/jira/browse/FLINK-11935
> I find a key code snippet has been removed in CALCITE-1884 which caused this issue :
> {code:java}
> if (j < 2299161) {
>    j = day + (153 * m + 2) / 5 + 365 * y + y / 4 - 32083;
> }
> {code}
