If you are getting warning message saying not to rely on system time zone , then add this line to the top.

date_default_timezone_set('America/Chicago');

$today   =  date_create('now');

echo $today->format('Y-m-d H:i:s');

Let us try tomorrow's date

date_default_timezone_set('America/Chicago');

$date =  date_create("now");

echo $date->format('d-m-y H:i:s');

echo "<br><br>";

$date =  date_create("tomorrow");

echo $date->format('d-m-y H:i:s');

Out put is here

17-01-21 21:54:26

18-01-21 00:00:00

Another way

date_default_timezone_set('America/Chicago');

$date = date_create('2013-07-19 23:16:30');

echo $date->format('Y-m-d H:i:s') ;

Output is here

2013-07-19 23:16:30
