The first thing I would do would be to verify that you can correctly process 
the desired data-products that are already in the product-queue. Extract the 
pqact(1) configuration-file entry into its own configuration-file and then 
execute pqact(1) manually -- specifying the configuration-file you just created 
-- and ensuring that the "time offset" option will cause any desired 
data-products in the product-queue to be process (verify that they do exist in 
the product-queue with an appropriate pqcat(1)). Make sure you execute the 
pqact(1) process in the right directory.
