A phone call to each base to email their duty sheets for the last twelve months would take an hour or two. Wait for the files to be sent - they will all be on computer, but it might take a day or two to receive them all.

So technically, yes, it will take more than 20 hours in total from initiating the request. You could also add in the time spent by every person involved at any stage of processing this request. It is amazing how the hours build up. Police officers are experts at stretching hours when there's overtime to be had.
