See attached. It's monthly data with date format "01/mm/yyyy", and I
guess the redundant leading "01/" confuses gretl.
Thanks, Sven. Gretl was trying to interpret the dates as MM/DD/YYYY. That
interpretation "works", but produces something that's not a sensible time
series (data for the first 12 days of each year) and therefore gets
So now in CVS if we don't get a sensible interpretation we try looping
back and using DD/MM/YYYY.
