contour recording times

I am getting conflicting recordings because the time of most of the recordings is not on the hour. For example a show that comes on at 8:00 pm is showing a recording time of 7:59 PM and an ending time of 8:31 PM instead of 8:30 PM. How do I adjust the time of the recording. Before we got Contour I could easily change the time as it was an option. There appears to be no option to do this with Contour.
