Be careful interpreting the log messages from pqact(1) and pqcat(1).
The product-queue is sorted by data-product insertion-time, but the
times printed by pqcat(1) and pqact(1) are the data-product
creation-time.  It's possible for a data-product to have an
insertion-time that is minutes off from it's creation-time (usually the
insertion-time is later, but clocks can be off).

More Monday.
