This appears to work:

import pywintypes
import win32file
import time

def set_dir_time(path, new_times=None):
    if new_times is None:
        t = time.localtime()
        atime, mtime = t, t
    else:
        atime, mtime = time.localtime(new_times[0]),
time.localtime(new_times[1])
    atime, mtime = pywintypes.Time(atime[0 : 6]),
pywintypes.Time(mtime[0 : 6])
    handle = win32file.CreateFile(path, win32file.GENERIC_WRITE,
win32file.FILE_SHARE_READ | win32file.FILE_SHARE_WRITE, None,
win32file.OPEN_EXISTING, win32file.FILE_FLAG_BACKUP_SEMANTICS, 0)
    win32file.SetFileTime(handle, None, atime, mtime)
    handle.Close()
