I use Square Payroll and do not believe this is an option.  You have to import timecards to payroll that have been made in the Square system.  If you're using a timeclock outside of square, you might ask yourself if it would be worth the $5/mo per employee to use their timeclock.  How much time will it take you to manually enter every shift for every employee?  Since I use both, my payroll takes me less than a minute.
