Can I set up time for the question to be answered here?
Simply override answer form and and add this if else before file:
$time_after_no_answer = 86400 // One days
if(current_time() > get_the_date('timestamp') + $time_after_no_answer)){
//answer-form.php contents here
}This above code will check if question time is greater then current time, then only answer form will be visible.
