Licensing for derivative works?

[bradland]

I'm interested in making a "sysadmin's clock" using clock19.svg as the base. This clock would have features that sysadmins -- who frequently deal with UTC, local time, and 24-hour formats -- might find useful. My desire would be to publish my work under the MIT license, but I don't see any licensing information in this repository. If it's not too much trouble, could you look in to adding a license to the repo? Thanks!
