This should be an easy pull, as it mimics normal unzip behaviour of extracting files with times from the zip file.

Python unzip does not modify the files date when extracting, so it gets the current time.

Looking good! I think all this needs is to polish the comments so they're self-contained and oriented toward the code-reader of the future rather than summarizing our discussion here, and it will be good to go.
