Coding style - you need more { }.   This also all needs to be
conditionally complied for the many platforms that don't provide the
clock API.

I don't think supporting clk_get_sys() is a particularly good idea
here...  Also, I think Liam was wanting to add per-user data to the
widget rather than reuse the priv pointer.

This appears to be *nothing* to do with the rest of the patch!  It's
also not clear what it's for.
