If you have a EB case then it will be processed in CSC, unless they decide (in rare cases like mine) to transfer your I-485 to the local office, in which case the EAD and AP will also be processed at the local office.
If your case is a family based case, then everything, including the EAD and AP will be processed at the local office.
The times posted at the local office are not for employment based cases.
