Where the time occurs depends whether you roll out on the time or wait till the time than roll. It takes a priod of time for the aircraft to start turning once the bank is applied and to stop turning. This can result in 5 deg off - if you are not rolling briskly.
**Turn - Time start rolling wings level on time
Time - Turn start rolling level before the time to be level on time.
