If your employer is using 7punches, you'll have the ability to access your timesheets to see exactly when you clocked in/out.
Here's how to access your timesheets:
1. Login to your account at app.7shifts.com
2. Go to My Timesheets
3. Select the period you'd like to view
Once you click on a date range, you'll be able to see your time clock in and out entries.
