> The error occur when {{timestampadd(MINUTE, 1, time '01:00:00')}} is executed:
> java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Long
> at org.apache.calcite.rex.RexBuilder.clean(RexBuilder.java:1520)
> at org.apache.calcite.rex.RexBuilder.makeLiteral(RexBuilder.java:1318)

> I think it should meet the following conditions:
> ||expression||Expect the result||
> |timestampadd(MINUTE, -1, time '00:00:00')|23:59:00|
> |timestampadd(MINUTE, 1, time '00:00:00')|00:01:00|
> |timestampadd(MINUTE, 1, time '23:59:59')|00:00:59|
> |timestampadd(SECOND, 1, time '23:59:59')|00:00:00|
> |timestampadd(HOUR, 1, time '23:59:59')|00:59:59|
> This problem seems to be a bug in calcite. I have submitted isuse to calcite. The following
is the link.
