Extract files from zip file and retain mod date?

Based on Jia103's answer, I have developed a function (using Python 2.7.14) which preserves directory and file dates AFTER everything has been extracted. This isolates any ugliness in the function, and you can also use zipfile.Zipfile.extractAll() or whatever zip extract method you want:

import time
import zipfile
import os

# Restores the timestamps of zipfile contents.
def RestoreTimestampsOfZipContents(zipname, extract_dir):
    for f in zipfile.ZipFile(zipname, 'r').infolist():
        # path to this extracted f-item
        fullpath = os.path.join(extract_dir, f.filename)
        # still need to adjust the dt o/w item will have the current dt
        date_time = time.mktime(f.date_time + (0, 0, -1))
        # update dt
        os.utime(fullpath, (date_time, date_time))

To preserve dates, just call this function after your extract is done.

Here's an example, from a script I wrote to zip/unzip game save directories:

        z = zipfile.ZipFile(zipname, 'r')
        print 'I have opened zipfile %s, ready to extract into %s' \
                % (zipname, gamedir)
        try: os.makedirs(gamedir)
        except: pass    # Most of the time dir already exists
        z.extractall(gamedir)
        RestoreTimestampsOfZipContents(zipname, gamedir)  #<--  USED
        print '%s zip extract done' % GameName[game]

Thanks everyone for your previous answers!

Well, it does take a little post-processing, but it's not that bad:

import os
import zipfile
import time

outDirectory = 'C:\\TEMP\\'
inFile = 'test.zip'
fh = open(os.path.join(outDirectory,inFile),'rb') 
z = zipfile.ZipFile(fh)

for f in z.infolist():
    name, date_time = f.filename, f.date_time
    name = os.path.join(outDirectory, name)
    with open(name, 'wb') as outFile:
        outFile.write(z.open(f).read())
    date_time = time.mktime(date_time + (0, 0, -1))
    os.utime(name, (date_time, date_time))

Okay, maybe it is that bad.
