Roughtime: Securing Time with Digital Signatures

This post introduces Roughtime, a new authenticated time service offered by Cloudflare. It addresses the critical problem of clock skew in client systems, which negatively impacts TLS certificate validation and overall internet security. Roughtime provides an accurate and secure time synchronization protocol that is auditable, making time servers accountable. Cloudflare's deployment of Roughtime aims to improve the validity of TLS artifacts they serve and contribute to a more robust Roughtime ecosystem.
