If your real table uses dates instead of timestamps modify the code
accordingly, they are not the same ( dates are countable, instants in
time are not (they are in the computer, with finite precision, but you
see the difference )) Although I supose they really are timestamps, or
you would have just used "date_column=current_date".

Happy hacking.
