consensus processed be a replacement for the system time?

there.

> However! That's a different issue. It's about making the '''update'''
step less dependent on things like system time, though we won't be able to
make it fully deterministic. Still a good thing to do. But it's different
from making the '''write''' step deterministic where we're taking a
`status/` directory as input and writing files to the `out/` directory.
Should we collect this idea on a new ticket, like, "Make updating status
files independent of system time"?
Oh, I took this ticket as meaning 'Make results from Onionoo
deterministic', but writing and updating are different concerns. Will
open a new ticket (rather with the meaning I perceived) and check for more
issues in the update process while continuing the review.
