  • • 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 (e.g., America/New_York).
  • • Drift is estimated using server time with RTT correction (half round-trip).
