Both the LDM and LDM networks depend on accurate clocks for 
correct operation.  The log message indicates that the data-product
arrived about 48 seconds before it was created.  Because the clock
on idd.unidata.ucar.edu is synchronized via ntpd(1), it is most
likely that the clock on c109-10 is slow.  I strongly recommend
that you use ntpd(1) to synchronize that clock.  This will eliminate
the log messages and help ensure that your LDM works correctly.
