Description

Our strictness in enforcing being within the 7-day signature validity period interacts badly with skewed clocks. Do we want to encourage signers to pre-date the signature's timestamp by X hours, or require clients to trust signatures that start being valid in X hours, or something else?

Contributor guide

Research direction
Research and evaluate approaches to handle clock skew in signature validity: pre dating signatures by X hours, trusting future start times by X hours, or other mechanisms. Consider trade offs and draft recommendations.
