How To Write Your Own Time Comparison Function in Ruby Like time_ago_in_words Without Rails

       

  # time_ago_in_words(Time.now, 1.day.ago) # => 1 day
  # time_ago_in_words(Time.now, 1.hour.ago) # => 1 hour
  def time_ago_in_words(t1, t2)
    s = t1.to_i - t2.to_i # distance between t1 and t2 in seconds

    resolution = if s > 29030400 # seconds in a year
      [(s/29030400), 'years'] 
    elsif s > 2419200
      [(s/2419200), 'months']
    elsif s > 604800
      [(s/604800), 'weeks']
    elsif s > 86400
      [(s/86400), 'days']
    elsif s > 3600 # seconds in an hour
      [(s/3600), 'hours'] 
    elsif s > 60
      [(s/60), 'minutes']
    else
      [s, 'seconds']
    end

    # singular v. plural resolution
    if resolution[0] == 1
      resolution.join(' ')[0...-1]
    else
      resolution.join(' ')
    end
  end
