In MDL-74775, we have fixed the code not to clear the original create time of the task.

For the startedtime column, we cannot do the same fix, because, at the moment, we're using that column to indicate which task is running in the system.

So, it would be safer to introduce a new column to log the original start of the task instead of modifying the current logic.

This feature will help a lot for MDL-79128 and MDL-79130

So Improvement should be good!
