Features? Well, you can create your own display using standard strftime variables, and I present a little area where you can see what the appropriate settings are and what they mean. There's also a couple of default formats you can choose if you don't want to make a custom version.
This doesn't compete with the fancier ones, but if you like other things I've written and feel comfortable with using this, too, then by all means go ahead. I don't plan to expand the functionality as this was something I wrote for myself and am releasing "just in case" someone else wants it, too.
