Add [Time] to [Finished On] field in [Import Source File] to confirm how long it took to import.

[Expected Result] Import end date and time should be shown in minutes or seconds units in [Settings] > [Data Management] > [Import] > [Import Source File] records so that customer can see the processing time required for the import. [Actual Result] Customer would like to check the processing time of import, however, the actual processing time is unknownable in minutes or seconds because import source files only record end date as [Finished On]. Also, customer cannot add time to [Finished On] field because the form of import source files is not editable.
