X Post Timestamp Verification
X Post Timestamp Verification. Verify when X posts were actually published. Timestamps are derived arithmetically from the snowflake id in each URL — no external API call, no model guessing. Unparseable URLs return null rather than an estimate. Useful for auditing whether cited evidence existed at a claimed time.
