It will need a bit of fiddling to get a timestamp out of the individual 
date-time fields so will not work directly with any of the existing 
wee_import sources without further massaging. But otherwise will be OK. 
That looks very much like the mYYYYlg.txt files I am working with, I have 
wee_import extracting the data from the mYYYYlg.txt log files, just need to 
pickup a few of the other log files and sort out some units and we should 
be ready for a trial. I'll drop you a line when I have something ready.
