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

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).
