The zipimport module checks the timestamp of a pyc file loaded from the zip file against the timestamp of a corresponding py file in the zip if any. This seems pointless. By the time someone has created a zip file for zipimport they should have guaranteed that the pyc's are fresh or not have put them into the zip file at all (wasteful). https://hg.python.org/cpython/file/e8878579eb68/Modules/zipimport.c#l1187 There is a comment in the code alluding to this, but the mtime check is still done right above.
