Time#times may help.  Sample:

  #! /usr/bin/env ruby
  cmd = ARGV.join(" ")
  b = Time.now
  system(cmd)
  e = Time.now
  ut, st, cut, cst = Time.times
  total = (e - b).to_f
  printf STDERR, "%11.1f real %11.1f user %11.1f sys\n", total, cut, cst

In addition Time class in general is pretty useful.
