Timert raises an error for the last day of the year

[mkwiatkowski]

The error was ArgumentError: argument out of range in last_second_of_day method when time is initialized with Time.new(2013, 12, 32, 0).

Quick fix I did, but maybe there is a better way:

    def last_second_of_day(timestamp)
      time = Time.at(timestamp)
      if time.month == 12 and time.day == 31
        Time.new(time.year + 1, 1, 1, 0)
      else
        Time.new(time.year, time.month, time.day + 1, 0)
      end
    end
