It's a larger problem to solve, and one that needs solving in a wider context than just CeroWRT, and so we should keep working on a solution, but not make it a "release blocking" issue.  It's a known issue, a known bit of research to continue chiseling away it, but not a major blocker.

This suggests using 'tlsdate', or the dhcp time option (if provided by another DHCP server):

tlsdate looks interesting, as you'd still have *some* protection from the TLS certificate check,
even if you patch it to fallback to an insecure DNS lookup.
