x402 APIPassing, checked 1 h ago
Resolve a local time to an exact UTC instant with explicit DST ambiguity handling, business-day arithmetic, public-holiday status, and working-hour overlap across timezones. Detects ambiguous and nonexistent local times instead of silently shifting them. Declares its IANA tzdb release and per-jurisdiction holiday provenance.
