The Time and Labor WorkCenter introduced in PeopleSoft 9.2, is probably one of the top features of the module in the new release. WorkCenters themselves have been part of previous Peopletools releases and one could argue that customers on an application release prior to 9.2 could easily create new workcenters for Time and Labor without having to move to 9.2. This is a valid argument, but from a practical perspective, I believe that a delivered workcenter for a module like Time and Labor will greatly help drive down the total cost of ownership and benefit a larger number of PeopleSoft T&L customers.
To truly understand the value of a workcenter in T&L, I think it is imperative to look at the tasks carried out by someone managing employees using Time and Labor in PeopleSoft. Given below is a generic list of period-end activities that a T&L manager would have to carry out in PeopleSoft:

1. Check if there is time and absence pending  approval.
2. Check if there are exceptions requiring attention and clear them.
3. Manipulate the timesheet of employees on an on-demand basis - correcting missing punches, incorrect punch order errors etc.
5. Make changes to work schedules as required. 
4. Run certain time consolidation and audit reports to ensure that there are no discrepancies in the time generated for the pay period.
