6 minute error in date-times

My script reports the time with a six minute error added to the current time. I can't figure out why.

I wrote a different script for solar calculation and get a 7 minute error subtracted. I'm hoping a response to this post will help me solve both problems.

I abbreviated the six minute error script to simplify the problem.

=====================================================

date_default_timezone_set("America/New_York");
$date = new DateTime();
$date4 = new DateTime();
echo(date("Y-m-d H:i:s"))."    date\n";
$now = new DateTime();
$timestring = $now->format('Y-m-d H:i:s');
echo($timestring)."    timestring\n";
$date2=date_create(date("y-m-d"));
$date4=date_create(date("y-m-d"));
date_add($date,date_interval_create_from_date_string("0 Hours"));
date_add($date4,date_interval_create_from_date_string("06 Hours"));
echo date_format($date2,"Y-m-d, H:m:s")."    date2\n";
echo date_format($date4,"Y-m-d, H:m:s")."    date4\n";

Yes. I ran :

echo(date('d-m-y h:i:s'))."  =  current date";

The correct result:

04-06-21 10:39:58   current date

I think the problem originates in the following command:

$start = date_add(date_create(),date_interval_create_from_date_string("6 hours"));

Correction:

The problem code:

$date4=date_create(date("y-m-d"));
date_add($date4,date_interval_create_from_date_string("06 Hours"));
echo date_format($date4,"Y-m-d, H:m:s")."    date4\n";

'Y-m-d' - months and 'H:m:s'  - minutes.

I added '0 minutes 0 seconds' to the format string with no change in the result.

I tried 'print' in addition to 'echo', with no change in the result.
