vinoyang created CALCITE-2989:
---------------------------------
Summary: The method ymdToJulian in DateTimeUtils returns wrong
value
Key: CALCITE-2989
URL: https://issues.apache.org/jira/browse/CALCITE-2989
Project: Calcite
Issue Type: Bug
Components: avatica
Reporter: vinoyang
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}
