    os.time()

    i have a problem with the os.times() command, on different Python
    versions, i get different printout:

    Server1# python

    and on the 3 servers, the linux command: $date
    returns the same value.....

    any suggestions???
    what is the command that gives me the actual time?

      time.time(), not os.times(). The latter is for process-times. No idea why it
      can become _negative, though.

          WANTED: reliable benchmarks to improve Python speed/performance estimation.
          REWARD: the thanks of the whole community.

          I spent some time at the recent Need For Speed sprint addressing
          benchmarking questions, and discovered that we need more benchmark tests
          for speed and perfomance. Sean Reifenshneider seems to be on the trail
          of one addition, but the, more the merrier. It's not easy to write good
          benchmarks ...

          regards
          Steve
