6 minute error in date-times

[jim2281950]

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";

Have you already checked that the server time is correct?

[jim2281950]

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";

What does "m" mean?

[jim2281950]

'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.

So if I tried to format as "mmm", what would it do? Months? Minutes? Combination of both?

Check the documentation, or look up earlier in your code to see what you should be using instead.

[jim2281950]

I wondered why the 'i' was used. Thought that was an option and 'm' was interpreted by context.

Changing to 'i' solved the problem.

Thanks requinix.
