Update field not replacing it's content if post date is changed

Hi, just wrote a code that adds 6 weeks to the post date, which is stored in another custom field. (trying to create a function that when that time in the future is there, the post category changes).

However I couldnt help but notice that once the value is saved, and the post date is altered, the custom field doesn’t update.

Is this a bug or am I missing something here ?

function my_acf_update_value( $value, $post_id, $field  ) {
	
	// override value
  
    $date = get_the_time( '', $post->ID );
    $value = (get_the_time ('U', $post->ID) + 3628800); 

    // do something else to the $post object via the $post_id
	
	// return
    return $value;
    
}

add_filter('acf/update_value/name=event_end_date', 'my_acf_update_value', 10, 3);

Try setting your priority higher

add_filter('acf/update_value/name=event_end_date', 'my_acf_update_value', 20, 3);

Also, I’m not sure what format the value needs to be in. A date field does not store a Unix time stamp, so this might be incorrect. get_the_time ('U', $post->ID) + 3628800 You need to figure out the format of the value that ACF is passing your filter and then return the correctly formatted value.
I would do this by temporarily adding

echo $value;die;

at the beginning of the function to figure out what I need to do.
