the result of the difference between two dates does it well if they are whole hours but without minutes it does not show me the correct data.THE CODE:

$r=strtr($marcacion->marcacion, '/', '-');
$date = date('Y-m-d H:i:s' , strtotime($r));
$dates = new DateTime($date);
$dteDiff  = $temporal->diff($dates);

the variable $temporal is the same case, just is the previous value. AND THE RESULT:

ID: 310 value temporal: 21-02-2017 07:30:00 AM ---
value dates: 21-02-2017 13:03:00 PM total time : 05:33 (should be 06:33)
ID: 310 value temporal: 23-02-2017 07:34:00 AM ---
value dates: 23-02-2017 13:06:00 PM total time : 05:32
ID: 316 value temporal: 14-02-2017 13:15:00 PM ---
value dates: 14-02-2017 17:15:00 PM total time : 04:00

Which result are you concerned about? – wedstrom Oct 24 '17 at 17:52
13:03:00 PM? Which is not true. Something is wrong. – Rutvij Kothari Oct 24 '17 at 17:57
Check [PHP find difference between two datetimes](https://stackoverflow.com/a/15688824/3226121) – ljubadr Oct 24 '17 at 17:58

13:03:00 PM? military format 24 hours @RutvijKothari – AtyFlow Oct 24 '17 at 18:11
No it shouldn't, you are adding the 30 when you should be subtracting – wedstrom Oct 24 '17 at 18:14
@AtyFlow 13:03:00 is in 24hour format, AM/PM doesn't make sense. – Rutvij Kothari Oct 24 '17 at 18:16
Ahh yes, but the total is correct no? – wedstrom Oct 24 '17 at 18:17
in the last case Yes, but no in the fisrt and second.. – AtyFlow Oct 24 '17 at 18:18
@RutvijKothari i just want to see, now i have change the format.. to: format('d-m-Y H:i:s') – AtyFlow Oct 24 '17 at 18:21
13-5.5=7.5, I think the math is fine. Further, 13:03 in military time is still technically PM time, I don't think we really have a problem here. – wedstrom Oct 24 '17 at 18:25
should be 7-13 =6 ?? in complete hours plus minutes (33) @wedstrom – AtyFlow Oct 24 '17 at 18:27

@AtyFlow 13:03:00 - 7:30:00 = 05:33 -> 7:30:00 + 5 hours = 12:30:00. Now, 12:30:00 + 33 minutes = 13:03:00 = 05:33. :D – Rutvij Kothari Oct 24 '17 at 18:31
OMG really thanks! I was not doing well, I'm sorry. Thanks for your time @RutvijKothari – AtyFlow Oct 24 '17 at 19:31
@AtyFlow It's okay. I was confused too. :). – Rutvij Kothari Oct 24 '17 at 22:26
