Hi Mike

You can go that route but it can take a while to generate & process the 
spoolfile. Depending on your situation (ie, if you have the authority), 
you might be able to read the log files directly. They are regular 
physical files in QSYS. The name is QHSTYYDDDX where YY is a two digit 
year, DDD is the julian date (days from start of year) and X is a 
sequencing letter (A then B etc throughout the day). The file has just a 
single field, SYSLOGFLD, where the first 10 bytes hold the date & time. 
As yet I haven't figured out how that's encoded but I'm sure someone else 
on the list will know.

We just have the one application that parses the logs, written a long time 
back. It uses the DSPLOG/CPYSPLF technique which is why I know it takes 
ages ;) If someone knows the method for extracting the date & time I can 
rework the app to speed it up :)
