Roughtime & IoT

[Bert Tilmans]

I'm in need for authenticated (rough) time synchronisation for IoT devices, for which Roughtime seems to be a good potential solution. Do you have any ideas on the timelines for when supported servers will be up&running and when (example) client code (C/C++) will be available, if any?

Hello!

So what's happened is that I've been pushing forward a roughtime draft
in the IETF, and sometime roughtime.cloudflare.com will update to the
latest draft version. Unfortunately this has some breaking changes.
Also some servers have had the wrong time, and this has caused
problems for other clients, so it's clear we need to do more work on
the ecosystem and monitoring.

I've mostly been implementing in Go.

Sincerely,
Watson Ladd

Hi,

Shameless plug but I just made a C version available at https://github.com/nahojkap/craggy

Some work still progress (like a proper test suite, cleanup of the docs) but would be great to get some early feedback.

Cheers,

Johan
