code: def new_timestamped_uid(bits=32):
    
    return "%s-%s" % (re.sub('[^\w.]', '', datetime.now().isoformat()).replace(".", "Z-"), new_uid(bits))
docs: A unique id that begins with an ISO timestamp followed by fractions of seconds and bits of
    randomness. The advantage of this is it sorts nicely by time, while still being unique.
    Example: 20150912T084555Z-378465-43vtwbx
