# Time.to_r (from ruby core) --- time.to_r -> a_rational --- Returns the value of *time* as a rational number of seconds since the Epoch. t = Time.now #=> 2020-07-20 22:03:45.212167333 +0900 t.to_r #=> (1595250225212167333/1000000000) This method is intended to be used to get an accurate value representing the seconds (including subsecond) since the Epoch.
