## Proposed changes ## Proposed changes In the previous code, we distinguished between two types of time, "time" and "timev2", but on the backend, both of them are the same. So here, we are making some modifications. The unit for "time" is seconds, while the unit for "timev2" is microseconds. Issue Number: https://github.com/apache/doris/issues/17174 Due to the mixed usage of "time" and "timev2" in many places in the past, this pull request will be **converted to a draft** first for regression testing. before ``` mysql [test]>select timediff( cast('0001-01-01 00:00:00.114514' as Datetimev2(6) ) , cast('0001-01-01 00:00:00.000000' as Datetimev2(6) )); +--------------------------------------------------------------------------------------------------------------------+ | timediff(CAST('0001-01-01 00:00:00.114514' AS DATETIMEV2(6)), CAST('0001-01-01 00:00:00.000000' AS DATETIMEV2(6))) | +--------------------------------------------------------------------------------------------------------------------+ | 00:00:00 | +--------------------------------------------------------------------------------------------------------------------+ ``` after ``` mysql [test]>select timediff( cast('0001-01-01 00:00:00.114514' as Datetimev2(6) ) , cast('0001-01-01 00:00:00.000000' as Datetimev2(6) )); +--------------------------------------------------------------------------------------------------------------------+ | timediff(CAST('0001-01-01 00:00:00.114514' AS DATETIMEV2(6)), CAST('0001-01-01 00:00:00.000000' AS DATETIMEV2(6))) | +--------------------------------------------------------------------------------------------------------------------+ | 00:00:00.114514 | +--------------------------------------------------------------------------------------------------------------------+ ``` <!--Describe your changes.--> ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
