CodeIgniter date - wrong time -

i'm using:

date("d-m-y h:i:s") 

in controller, time later actual time. example, in country it's 01:02, date return 20-06-2015 01:06:38.

how fix it?

1st step : go config/config.php , write

//specify region  date_default_timezone_set('europe/warsaw'); 

2nd step: can use time

date("d-m-y h:i:s") //for 21/12/2010 20:12:00 date("h:i:s") //for 12:12:11 time
