ruby on rails - Result of time subtraction? -


How do I get the result of subtraction in words like "7 seconds"? StuffTime is not working because the result is fiction. 

  a = time.nough: b = time.new # a few seconds later b - a # 7.17584 (seconds)    
 < div class = "post-text" itemprop = "text"> 
 If you are using rail, you can use it:  
  from_time = time.one distance_of_time_in_words (Se_time, se_time + 15 seconds, included_scond: true) less than # 20 seconds
