Notes

• Deep links: ?epoch=1726920000&unit=s&tz=America/New_York or ?date=2025-09-21T12:30:00&tz=UTC.
• Auto-detects epoch unit (s, ms, us, ns). You can force a unit if needed.
• Time zone must be a valid IANA ID such as America/New_York.
• Drift is estimated using server time with RTT correction (half round-trip).
