How this could be done? Give me an hint and I'll procede by myself!
Thank you!
I think row.field.date() already works because row.field is a datetime

return dict(rows=rows)
throws an exception complaining that
Thanks Massimo!

I have to exctract some statistics from a radius accounting table that
is generally a really big table.
After exctracting tha data, i pass it to jqplot.com via a json service
to be rendered.
For some graphics, I have to exctract a big amount of dates from
accounting
