Mine's very similar, and includes the current date and time; it also wraps onto the next line and starts with a # (mostly because I'm an idiot, and have burned myself by copying-and-pasting an entire-line-plus-newline and ran a command instead of just copying it in order to edit it.)

    [\[\033[1;32m\]\D{%Y-%m-%d %H:%M:%S}\[\033[0m\]] \[\033[1;32m\]\u\[\033[0m\]\[\033[1;32m\]@\h\[\033[0m\]:\[\033[1;36m\]\w\[\033[0m\]\n#

It's actually dynamically generated by my .bashrc so that different servers have different colors; at a glance, I can generally tell whether I'm on one of my machines, or on a work build server, or an amazon ec2 instance.
