Using ESS Time Entry When Paying Salaried Non-Exempt Employees Current

We currently pay our salaried non-exempt employees for 80 hours per pay period, but make any adjustments for overtime or for working less than 80 hours on the next pay check because we pay them current and don't know what their hours are going to be for the remainder of the pay period when we run our payroll.

These adjustments are made manually by our Payroll department based on timecard information the employees enter in Excel.

I've been assigned a project to explore using Employee Self Service Time Entry for these employees so we can automate this process.

The problem that I have is that if we continue to pay the employees current, then the timecards that are created from the ESS Time Entry records won't be in the pay period being processed by the payroll.  Has anyone else dealt with this issue?
