Known IANA zones, explicit unknown-zone reasons, provider offsets, source observations, local chronology, and overnight evidence stay together while display conversion and schedule freshness remain host responsibilities. This is the real published Genesis interface—not a stock image.

Cruise Port Call Local-Time Provenance Codec
Preserve cruise port-call local clock values with explicit zone status, provider offset, and observation provenance instead of silently reinterpreting them through a device time zone.
An original dependency-free codec for cruise itinerary boundaries. It validates real local calendar values, canonicalizes seconds without turning wall-clock evidence into an instant, records a valid IANA zone or an explicit unknown-zone reason, preserves a provider-supplied UTC offset and source observation, checks local chronology, derives overnight calls from dated evidence, and returns deeply frozen records plus stable JSON.
Preserve cruise port-call local clock values with explicit zone status, provider offset, and observation provenance instead of silently reinterpreting them through a device time zone.

- Frozen deterministic records with chronology and overnight checks
What this specific product actually does
Every Genesis listing has its own capabilities, workflow, automation status, limits, and proof standard—without generic promises copied from another product.
Inside Cruise Port Call Local-Time Provenance Codec
- 01Accepts arrival-only, departure-only, and paired port-call evidence using real local calendar values in minute or second precision.
- 02Requires known zones to carry a valid IANA identifier and unknown zones to carry a bounded reason instead of guessing from a port code.
- 03Preserves an optional provider offset within ±14:00 and a required RFC 3339 source observation timestamp with an optional traceable reference.
- 04Canonicalizes local values to seconds without treating them as instants or applying the executing device's time zone.
- 05Rejects backwards local chronology and verifies or derives the overnight marker when both full local dates are present.
- 06Returns immutable normalized records, stable JSON, bounded value-free validation issues, and performs no I/O or mutation.
Port-call local-time provenance without schedule or timezone assumptions.
The codec validates and preserves supplied local-time evidence only; the host owns provider authorization, freshness, conversion, rendering, notifications, publishing, monitoring, and rollback.
This product does not modify a customer website.
Who this is built for
- 01Cruise itinerary ingestion that must preserve provider-reported local port times
- 02Floot and React applications separating schedule evidence from display-time conversion
- 03Teams that need explicit unknown-zone and source-freshness boundaries before itinerary publication
How you receive it
GCD-BVC-435
Verified ZIP · 15 files · JavaScript + TypeScript declarations + 36 tests + README + START-HERE
All Platforms, Floot, React / Next.js
Free
This listing is a downloadable Genesis code package. The ZIP includes reusable code and START-HERE directions.
Three steps for this product
- 01
Map authorized schedule evidence
Supply the provider's local clock value, explicit known or unknown zone state, optional reported offset, and a traceable observation timestamp.
- 02
Preserve the wall-clock boundary
Store the returned record as local evidence; never parse localDateTime with new Date(), and route issues to reviewed operations without guessing.
- 03
Stage, publish, and monitor
Test provider-specific date-line and daylight-saving fixtures, verify freshness and rendering in staging, publish through the host workflow, and retain rollback.
Before & After Repair Report
Cruise Port Call Local-Time Provenance Codec · GCD-BVC-435
Report format preview. Scores and status values populate only from measurements produced by an actual run. Genesis does not invent improvements.
What Genesis Code Doctor fixed
- Only verified changes appear here.
- Each repair can show affected files, routes, checks, or rules.
- Regression checks are recorded separately from the repair itself.
Still needs attention
- Unresolved, blocked, unavailable, or not-tested items remain visible.
- Evidence links can explain why an item passed, failed, or needs review.
- Follow-up verification can be run after implementation.
Know the fit, evidence, and handoff before a repair is used.
These controls turn a code product into a traceable repair workflow. They do not claim compatibility or success that has not been verified.
Declared support is available
Declared platforms: All Platforms, Floot, React / Next.js
Exact compatibility still depends on the customer's framework version, dependencies, hosting, custom code, and current site state.
Lifecycle protection is part of the product standard.
- Compatibility is reviewed before release.
- Regression and rollback requirements stay explicit.
- Follow-up verification can be run after implementation.
Genesis keeps the recommendation tied to evidence.
- Confirm the observed problem.
- Check product fit and safety boundary.
- Apply only the authorized repair scope.
- Re-run equivalent checks before calling it fixed.

The handoff includes product identity, declared compatibility, delivery method, capabilities, safety boundary, and the verification sequence.
What this item does not claim
This package does not fetch provider schedules, verify current port time, decide whether a cruise schedule is correct, convert arbitrary time zones for display, update itineraries, promise a connection, send notifications, or publish data. The host owns authorized provider data, freshness, daylight-saving and date-line context, rendering, notifications, publishing, monitoring, and operational review.
