Bug fixes: changes to static broke us, and the stack reversal we did broke FCO

- Changes to static made some parts of preview look funny. Fix that.
- Oliver and I did work last week to display a stacked graph. We reversed the stack, which broke FCO. We now revert the changes we made to tests, so that they break again, and then fix them properly.
- We mucked about with timezones a bit to fix the FCO labelling.
