> Reporter: vinoyang
> Priority: Major
> Labels: pull-request-available
> Time Spent: 20m
> Remaining Estimate: 0h

> 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}
