We understand how important it is to keep a record of timesheet activity for reference,  accountability, and not to mention, compliance. Because of this, we have added a timesheet change history that documents the who, what, and when for all timesheet entries and edits. You will notice a new icon in the top right corner of the timesheet, that when clicked, you can see all historical events for each day on the timesheet.
