Comment (by redneb):

 I have a patch for this issue that is basically ready. The only thing
 preventing me from submitting it is the fact that when
 `getFileAttributesExStandard` was added in Win32 the version number was
 not bumped properly. Because of that, I cannot use the MIN_VERSION_Win32
 macro which is needed in order to provide a version of
 `getModificationTime` that works with all version of the Win32 package. If
 you bump one of the first 3 components of the version number of Win32,
 then I will finish and submit my patch. See also [1].
