After going a bit nuts with the old text editor, I've made a
rudimentary implementation of this. I'll post the patch shortly. At
the moment I'm writing the time to a file on both the rockbox and PC,
but it would be slightly nicer to access the file creation times from
the filesystem instead. Unfortunately I can't find a function to do
this - does one exist, and if not, where would I start looking for
this?

Cheers,
