Extract files from zip file and retain mod date?

Question

I'm trying to extract files from a zip file using Python 2.7.1 (on Windows, fyi) and each of my attempts shows extracted files with Modified Date = time of extraction (which is incorrect).

import os,zipfile outDirectory = 'C:\\_TEMP\\' inFile = 'test.zip' fh = open(os.path.join(outDirectory,inFile),'rb')  z = zipfile.ZipFile(fh) for name in z.namelist():     z.extract(name,outDirectory) fh.close() 

I also tried using the .extractall method, with the same results.

import os,zipfile outDirectory = 'C:\\_TEMP\\' inFile = 'test.zip' zFile = zipfile.ZipFile(os.path.join(outDirectory,inFile))         zFile.extractall(outDirectory) 

Can anyone tell me what I'm doing wrong?

I'd like to think this is possible without having to post-correct the modified time per How do I change the file creation date of a Windows file?.

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.
