> 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

> I think it should meet the following conditions:

> |timestampadd(SECOND, 1, time '23:59:59')|00:00:00|
> |timestampadd(HOUR, 1, time '23:59:59')|00:59:59|
