I strongly disagree that automatic guessing of date format is a good idea:
Martin, I think either you misunderstood what I wrote or I was not sufficiently explicit in my brief response. I did not mean to imply there was any automatic guessing involved. Specifying input and output formats is required. Reading Hadley's book I was impressed that one could specify the format of dates in the dataset and convert them all to the ISO-8601 format. Before learning this I'd use emacs regex to do the reformating I needed (or, sometimes, awk).
