Why require "date"?

Time.now.strftime("%Y-%m-%d")   # => "2002-07-09"

For logfile naming using timestamps, I tend to use:

filename = "my_log"
logfile = "#{filename}#{Time.now.strftime("%Y-%m-%d-%H-%M-%S")}"

If I'm creating temp files, I like to handle multiple files per
second, so I kludged this:

filename = "/dir/tempfile"
tempfile = "#{filename}#{Time.now.strftime("%Y-%m-%d-%H-%M-%S")}#{(60000*rand).to_i}"

There's probably a better way to do the latter ...
