why does smarty function date_format get wrong time

Question

echo date('Y-m-d',time())

i get 2012-07-16 ,but when smarty output is

{$smarty.now | date_format : "%Y-%I-%d"}

i get 2012-04-16

I have been sured the time_zone is seted right.

Answer 1

Because %I is hours ... try :

{$smarty.now | date_format : "%Y-%m-%d"}

%m - month as a decimal number (range 01 to 12)

Docs are here for date_format
