Thank you, again. So I suppose it's possible that both cameras were way out, depending on their set up. I would have thought police would have checked the accuracy beyond merely comparing the outside camera to the inside camera, but there seem to be some basic things they didn't do in this case so not impossible that they didn't.
Again, it's not the cameras themselves that are 'out' it's the DVR that they are connected to. So, if there is just one DVR catering to all cameras at a location, then all video recorded from them will be 'out' by the same amount.
OTOH, if cameras are split over two or more DVRs -- and that would usually only be the case for a large system -- then video of the same event taken from different DVRs could be timestamped differently depending on the accuracy of the (unsynchronized) DVR clocks.
