- (Object) approximate_distance_of_time_in_words(from_time, to_time = Time.now, include_seconds = true)

Get the approximate disntance of time in words from the given from_time to the the given to_time. If to_time is not specified then it is set to Time.now. By default seconds are included…set the include_seconds argument to false to disable the seconds.

- (Object) distance_of_time_in_words(from_time, to_time = Time.now)

Return the distance of time in words from the given from_time to the specified to_time. If to_time is not specified then Time.now is used. By default seconds are included…set the include_seconds argument to false to disable the seconds.
