Yes, as mentioned by venkatesh yadav, you can generate Wage Types during Time Evaluation, even if you are on negative time.
Any information that can be gathered during Time Evaluation can be transfered to Payroll through table ZL, but most of these usually are "Information" Wage Types that will help make decisions during Payroll Calculation or that are required for Payroll Reporting. Yet, some of these Time Wage Types can be used to generate payments.
