Thanks Simon, now it makes sense. My (wrong) assumption was that fetch
would have returned the data with the desired resolution where
available, and filled with NaN the rest --since data with that
resolution was actually available, even if for a smaller intervall than

I tried with -s 1290435000 -e 1290615000 -r 300, and fetch returns CDP
with a 300s interval, as expected. Thanks!
