Can modified dates be modified?

Is it possible to modify a file and either (a) retain the previous modified date, or (b) reset the modified date to the previous modified date - i.e. make a change to a file in such a way that the change couldn't be detected by date modified?

I have a vendor who supplies batches of image files. When any of the files are changed, I receive a full re-delivery of the batch. I only want to update the changed files at my end, so sorting the files by date modified seems a logical approach.
However, if perhaps they were unscrupulous and wanted to update some other files that maybe had errors and they didn't want anyone to know, could they update those too, somehow retaining the previous modified date, so that nobody would know?
Obviously if this is possible and they're making changes on the fly, my technique of sorting by date modified is not an effective strategy.
