Julian Hyde commented on CALCITE-2989:
--------------------------------------
Also, could you change the summary of this issue to reflect what you're fixing?
The component should now be "core", not "avatica", right?
We should get this into the next Calcite release if you can make the javadoc /
test structure changes I requested above.

> 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}
