Label route-note timestamps with their actual zone
Visit notes appear an hour early after an emulator zone change. Distinguish stored instants from displayed local times.

Field percentages are editorial estimates of the ticket's engineering focus. They total 100%; they are not measured time, proficiency scores, or ownership evidence.

The board opens an editable draft; nothing is saved until you confirm it. Sign-in and workspace permissions apply, and Demo boards remain ephemeral.
Project context
Fictional maintenance coordinator Elm dispatches non-safety-critical inspection visits. Implement a mobile application in an emulator with local API stubs; physical devices and credentials are unnecessary.
Setup prerequisites
- Create synthetic visits and a local sync adapter.
- Provide controllable connectivity and process-restart simulation.
Preceding work
No earlier ticket is required. Complete the project setup above.
Acceptance criteria
- Instants remain UTC
- Display identifies zone
- Invalid timestamps show unavailable
Implementation constraints
- Inject time and zone in tests.
Verification to include
- Change emulator zone
- Render malformed timestamp
Deliverables
- Timestamp formatter and cases
Rollout and recovery
Restore UTC display if local conversion fails.
Value of the work
For the engineer: Practice durable mobile state and explicit sync conflicts.
For the team: Inspect how an engineer protects field work during disconnection.
Evidence boundaries
Outcome Evidence: Tests, patches, and runbooks are requested deliverables. They become Outcome Evidence only through a qualified Mission and immutable Evidence IDs.
Ownership Evidence: Independent adaptation must be observed under a declared verification policy and cite immutable Evidence IDs. Completing a planning ticket establishes no Ownership Evidence.
