Because you started with an empty queue, the first delivered product
should be the oldest one in the upstream queue that was inserted
there no earlier than 150 seconds before 02:29:30 UTC (150 seconds =
120 seconds + 30 seconds of "slop").  It could be that the product
in question arrived late at the upstream LDM -- although it should
have been filtered-out by the "from" time in the product-class
and should not have been sent.

Unfortunately, comparing the times encoded in product-identifiers
with the times in log messages is difficult because the two times
have different origins and don't need to correspond.

I just tried the command "ldmadmin -v -o 300" on the latest version
of the LDM and it performed correctly according to the log file.

Regards,
Steve Emmerson
