Sorry, but I couldn't resist the golfing opportunity! (I always learn something..)

start = Time.now.to_i
l = ->_{ puts Time.at(Time.now - start).utc.strftime("%T")[1..-1] + ": " + _ }
ARGF.each(&l)
l['DONE!']

Or saner/more conventional:

start = Time.now.to_i

ARGF.each do |line|
  puts "#{Time.at(Time.now - start).utc.strftime("%-k:%M:%S")}: #{line}"
end
puts "#{Time.at(Time.now - start).utc.strftime("%-k:%M:%S")}: DONE!"
