> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.17.0, 1.18.0
> Reporter: xuqianjin
> Assignee: Julian Hyde
> Priority: Major
>
> Two errors occur when {{timestampadd(MINUTE, 1, time '01:00:00')}} is executed:
> # The return result can only be of {{TimeStamp}} type and is expected to be of {{Time}} type
> # The return value is {{1970-01-01 01:01:00}}, and the expectation is {{01:01:00}}
> # Compared with {{mysql}} database, I think it should meet the following conditions:
> ||expression||Expect the result||
> |timestampadd(MINUTE, -1, time '00:00:00')|-00:01:00|
> |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|
