def art8601_format(dt):
    """
    Format datetime object in ISO 8601 format suitable for Artifactory.

    Artifactory's ISO 8601 timestamp parser is strict. It only accepts
    3 sigificant digits of sub-second precision (milliseconds) instead
    of the 6 significant digits (microseconds) in datetime.isoformat()
    output.

    I've raised a support ticket asking JFrog to consider relaxing
    their parser.

    Code adapted from standard python library.
