A time point plus a long time, how to calculate it

For example, the release time of a movie is 22:50:00, the total length of the movie is 01:40:00, so how to calculate the final end time?

Reply to discussion (solution)

$date = new DateTime (' 22:50:00 '), $date->add (New DateInterval (' pt01h40m00s ')), Echo $date->format (' h:i:s ');

00:30:00

Is this method only for moderators 01:40:00 this need to be converted?

That's fine.

echo Date (' H:i:s ', strtotime (' 22:50:00 ') + strtotime (' 01:40:00 ')-strtotime (' 00:00:00 '));

00:30:00

Call to undefined method Datetime::add () That's not the way.

That's fine.

echo Date (' H:i:s ', strtotime (' 22:50:00 ') + strtotime (' 01:40:00 ')-strtotime (' 00:00:00 '));
