The Manage Time screen lists all the time entries saved for your firm. It defaults to time entries posted today. Use the Quick Filter dropdown to load different date ranges. If you want to see more time entries than are available on the Manage Time screen, you'll need to use one of the Aero Reports.
You can toggle to view time sync information by clicking the Sync Info button.
Click the Time button on a time entry to edit that time entry or click the Aero button on a time entry to edit the associated Aero.
