Yes indeed!  Thank you very much, Hugh, and all
others who have helped!  The processing time is
now a flat 26 seconds, which sure beats the original
9 minutes!!!

To summarize, the three most significant speedups:
1) Only process 20% of the lines based on a quick check
    of relavency
2) Switch from using 'Date' class to 'Time' class
3) Minimize substring processing

Thanks again to all who have helped!
