Extract email attachments and retain modification/creation date?

I'm trying to extract files from emails via IMAP using Python 3.7 (on Windows, fyi) and each of my attempts shows extracted files with Modification & Creation Date = time of extraction (which is incorrect).
As full email applications have the ability to preserve that information, it must me stored somewhere. I also gave working with structs a try, thinking the information may be stored in binary, but had no luck.

import emailfrom email.header import decode_headerimport imaplibimport osSERVER = NoneOUT_DIR = '/var/out'IMP_SRV = 'mail.domain.tld'IMP_USR = 'user@domain.tld'IMP_PWD = 'hunter2'def login_mail():    global SERVER    SERVER = imaplib.IMAP4_SSL(IMP_SRV)    SERVER.login(IMP_USR, IMP_PWD)def get_mail(folder='INBOX'):    mails = []    _, data = SERVER.uid('SEARCH', 'ALL')    uids = data[0].split()    for uid in uids:        _, s = SERVER.uid('FETCH', uid, '(RFC822)')        mail = email.message_from_bytes(s[0][1])        mails.append(mail)    return mailsdef parse_attachments(mail):    for part in mail.walk():        if part.get_content_type() == 'application/octet-stream':            filename = get_filename(part)            output = os.path.join(OUT_DIR, filename)            with open(output, 'wb') as f:                f.write(part.get_payload(decode=True))def get_filename(part):    filename = part.get_filename()    binary = part.get_payload(decode=True)    if decode_header(filename)[0][1] is not None:        filename = decode_header(filename)[0][0].decode(decode_header(filename)[0][1])    filename = os.path.basename(filename)    return filename

Can anyone tell me what I'm doing wrong and if it's somehow possible?
After getting said information it could be possible to modify the timestamps utilizing How do I change the file creation date of a Windows file?.
