    Details:
        - Layer: ``181``
        - ID: ``19C2F763``

    Parameters:
        pts (``int`` ``32-bit``):
            PTS, see updates.

        date (``int`` ``32-bit``):
            date, see updates.

        qts (``int`` ``32-bit``):
            QTS, see updates.

        pts_limit (``int`` ``32-bit``, *optional*):
            PTS limit

        pts_total_limit (``int`` ``32-bit``, *optional*):
            For fast updating: if provided and pts + pts_total_limit < remote pts, updates.differenceTooLong will be returned.Simply tells the server to not return the difference if it is bigger than pts_total_limitIf the remote pts is too big (> ~4000000), this field will default to 1000000

        qts_limit (``int`` ``32-bit``, *optional*):
            QTS limit
