Re: Age function

Thanks for the daylight savings tip. However:

SELECT age('10/10/02' :: date, '1/10/02' :: date);
8mons 30days 23:00

SELECT age(date('10/10/02'), date('1/10/02'));
8mons 30days 23:00

When I cast to date, I should get 9 months.
It looks like it works timestamp, with hours and fractions thereof set to
zero. It should not take into account daylight savings, either.
I searched the archives, and this topic has come up more than once over the
past two years.
