The above message contained the following:

> The version on the downstream node is 6.3.0.

Then the "from" time in the request-for-data that a downstream LDM makes
will be the more recent of

    1.  The current time minus the "maximum age".  The "maximum age" is
        either

            A.  The argument of the "-o toffset" option, if specified; 
                otherwise,

            B.  The argument of the "-m max_latency" option (default
                3600 seconds).

    2.  The creation-time of the last, successfully-received
        data-product from the upstream LDM.

The logic for this is contained in the function prog_requester() in the
file "src/server/acl.c".
