Sum of time with cents

[AlexGentili]

this works great and does what it should, but if I had a time format with cents, for example
10:00:00.00 I can't make the change, any ideas?

// convert your date to DateTime object

$date = '10:00:00';
$dt = new DateTime($date);
// convert your period to 
DateInterval$hours = '00:25:10'; 

/* this data dynamic */

$parts = explode(':', $hours);
$interval = new DateInterval('PT' . (int)$parts[0] . 'H' . $parts[1] . 'M' . $parts[2] . 'S');

// Add interval to date
$dt->add($interval);// Format date as you needecho $dt->format('H:i:s');

cents?  As in "dollars and cents"?   Added to a datetime value?  Why ever would one want to do that?

AFAIK, DateTime and DateInterval only work with whole seconds. If you want to go smaller you'll need microtime()

I assume you mean milliseconds. Can you describe what you are trying to accomplish? I.e. do you need\want to include milliseconds or is the problem that there is input data with milliseconds that is causing a failure? The solution to your problem could be very different based on what you are trying to accomplish.

The manual shows that the DateTime class does support milliseconds. So, "where" in your code are you wanting to support milliseconds? Will it be the $date, will it be the defined interval, and/or do you need the milliseconds included in the output??? Need some more info.

Apparently the DateInterval class supports milliseconds, but the default method does not support it as an input value. You need to instead use the createFromDateString class of that method

// convert your date to DateTime object
$date = '10:00:00.500000';
$dt = new DateTime($date);
// convert your period to 
$interval = '00:25:10.300000';

//Extract time parts
list($hours, $minutes, $totalSeconds) = explode(':', $interval);
list($wholeSeconds, $milliSeconds) = explode('.', $totalSeconds);

//Create interval with milliseconds
$intervalString = "{$hours} hours + {$minutes} minutes + {$wholeSeconds} seconds + {$milliSeconds} microseconds";
$interval = DateInterval::createFromDateString($intervalString);

// Add interval to date
$dt->add($interval);// Format date as you needecho $dt->format('H:i:s'); 

echo $dt->format('Y-m-d\TH:i:s.u'); //Output: 2021-11-12T10:25:10.800000
