There are a couple of possibilities:

    1.  Your system clock could be off.

    2.  The connection to papagayo.unl.edu and nereid.eas.slu.edu
        could be poor -- resulting in poor performance and many
        disconnections.  This, when coupled with a bug in version 6.0
        of the LDM, could result in the reception of unreasonably old
        data-products.  The solution to this is to ensure that the
        connections have sufficient bandwidth and, possibly, upgrade to
        version 6.1 of the LDM.
