php - Add in an array records from today and tomorrow

Up to here everything makes sense... My problem is that when I need to display the movies of the day, I actually need to include the movies that will be broadcasted until the next day at 06:00.

So, for example, when I display the movies of Monday 7/12, I need to be displaying movies from Monday 7/12 06:00 up to Tuesday 8/12 05:59

(All hours mentioned above are 24-based)

How do I add this time offset?

The code I've written (that programmatically works 100% correct, except for that it doesn't take the time offset into consideration) is below (I've commented any part I felt might confuse you):

$posts = get_posts(array(
    'post_type' => 'movie',
    'numberposts' => -1, // This simply takes ALL records
    'orderby' => array(
        'ID' => 'ASC',
    ),
));

foreach ($posts as $post) {
    $broadcasts = get_field('movie_broadcasts', $post->ID); // This is the command to get the ACF Repeater field data for each movie

    if (is_array($broadcasts) && count($broadcasts)) {
        foreach ($broadcasts as $broadcast) {
            $timestamp = strtotime($broadcast['broadcast_date'][0] . ' ' . $broadcast['broadcast_time']); // Here I'm calculating the timestamp to limit below the movies that their broadcast happened in the past

            if ($timestamp > time()) { // Here is where I limit past movies, AND I think here is the correct place to somehow add that time offset maybe?
                $program[$broadcast['broadcast_date'][0]][] = array( // Here I "group" movies from the same day to a sub-array, and that where movies from tomorrow until 05:59 actually need to be added to
                    'movie' => $post->post_title,
                    'url' => get_permalink($post->post_id),
                    'channel' => $channels[$broadcast['broadcast_channel']],
                    'time' => $broadcast['broadcast_time'],
                    'poster' => get_field('movie_poster', $post->post_id),
                );
            }
        }
    }
}

array_multisort(array_map('strtotime', array_keys($program)), SORT_ASC, $program); // Here I'm sorting the days correctly

foreach ($program as &$day) {
    array_multisort(array_column($day, 'time'), SORT_ASC, array_column($day, 'movie'), SORT_ASC, $day); // And here I'm further sorting the movies from each day according to their broadcast time - and according to their title in case they are scheduled to air at the same time (in a different channel of course)... Also, this sorting will cause further trouble when the movies from the next day will be included to the movies of today, as their broadcast time ie. 01:30 will be smaller than the broadcast time of a today's movie ie. 21:00 
}
Copy code

Generally the whole code needs re-consideration and re-work... Can someone help me with this? TIA
