SAP Rescheduling (V_V2) Sort order

Hello experts!

have a question on rescheduling sort order:

1) Date -> Sort item by date of creation - Does SAP will consider only date? Or time also considered?

2) Document number - Does SAP takes real document number? What will happen if my sales orders have different number ranges in the same plant? (ex. Range one starts from 46......01; Range two starts from 45.....01) Does that mean that my 46.....01 will be prioritized first?

Thank you for your answers!
