There are lots of packages for date-time computations. What is the best one for timing computations for benchmarks? I'm thinking I want to fetch the time in 64 bit format instead of year, mo, day, hour, min, sec, nano seconds (which is what most of the date-time packages do). That should make subtraction faster. After I subtract two absolute times, then I want to display them in seconds.
Thanks, Siegfried
