wp_schedule_event custom event time

Question

Ok, let's say I want to give the user the ability to schedule a wp cron event every X minutes. Now, let's say I want X to be anywhere from 10 to 525600 (minutes in a year).

What I'm seeing is an utterly stupid way to handle cron events through the $schedules array. If I understand correctly, I have to add a custom schedule to the array for every single different event time the end user wants. For example:

add_filter( 'cron_schedules', function ( $schedules ) {
$schedules['twelve_minutes'] = array(
   'interval' => 12,
   'display' => __( 'Twelve Minutes' )
);
return $schedules;
} );

Please tell me there's some way to schedule an event with a custom time without having to add 525,590 unique intervals to the $schedules array.

Answer 1

I use the following code to run a task. this doesn't require adding a cron schedule.

function setup_my_action() { 
  if (!wp_next_scheduled('my_action')) {
     wp_schedule_single_event(time()+3600, 'my_action');
  }
}
function my_action() { 
  // do something
}
add_action('init','setup_my_action');
add_action('my_action', 'my_action');
