Great app! I'm interested in seeing the DateTime clock and the Decimal clock be configurable such that I could put an arbitrary strftime-compatible string in to get whatever date/time formats I want. Also, I would really like to see support for fractional days (probably I would pre-process %J into millidays so that it remains compatible with normal strftime syntax).

I am willing to write the code for this. Is a patch to this effect likely to get accepted? Is there a public source repository or other good thing or are hackers just extracting python from the .deb and using diff?
