Operational Time Machine
Timeline playback, evidence synchronization, and historical state reconstruction for operational auditing and incident investigation.

Operational Time Machine
The Operational Time Machine allows operators, supervisors, and auditors to replay any moment in facility operations. By leveraging the event-sourced architecture, Certexi can reconstruct the exact state of the warehouse at any point in time.
Live Demo
Watch a transport unit's complete journey from customs entry to exit clearance. The map, evidence panel, and timeline are perfectly synchronized — click anywhere on the timeline to jump to that moment.
TU-2025-004 — synchronized map + evidence chain + timeline scrubber.
Concept
Every action in Certexi — placement, removal, scan, inspection, weight reading — is recorded as an immutable event with a precise timestamp. The Time Machine replays these events chronologically to reconstruct past states.
Timeline Playback
Controls
- Scrub bar — Drag to any point in time
- Play/Pause — Animate through events at configurable speed (1x, 2x, 5x, 10x)
- Step forward/backward — Move one event at a time
- Jump to event — Click any event in the timeline to jump directly
- Time presets — Last hour, last shift, last 24 hours, custom range
Synchronized Views
When the playback position changes, all views update simultaneously:
- Map view shows asset positions at time T
- Kanban board shows transport unit stages at time T
- Evidence panel shows photos and clips captured around time T
- Metrics dashboard shows KPIs as of time T
Evidence Synchronization
The Time Machine correlates all evidence types for a given moment:
| Evidence Type | Synchronization Method |
|---|---|
| Photos | Matched by capture timestamp ± 30 seconds |
| CCTV clips | Matched by camera zone and time window |
| Scale readings | Matched by transport unit and timestamp |
| NFC scans | Exact timestamp match |
| Operator notes | Matched by event association |
Use Cases
Incident Investigation
When a discrepancy is discovered — missing seal, weight variance, unauthorized access — investigators can:
- Set the Time Machine to the time of interest
- View the warehouse state at that moment
- Review all evidence captured around that time
- Trace the chain of custody for specific assets
- Generate a forensic report with timestamped evidence
Audit Preparation
For ISO 9001 and customs authority audits:
- Demonstrate complete traceability for any transport unit
- Show exact workflow states during any period
- Provide synchronized evidence packages
- Export timeline segments as compliance reports
Operational Review
Supervisors use the Time Machine for shift handover and performance review:
- Review throughput during specific shifts
- Identify bottleneck patterns over time
- Verify that procedures were followed correctly
- Compare operational patterns across periods
Technical Implementation
State reconstruction uses the same event-replay mechanism as the WHMS:
function reconstructState(targetTime: Date) {
const events = queryEvents({ before: targetTime, orderBy: 'timestamp' });
return events.reduce((state, event) => applyEvent(state, event), initialState);
}
Performance
For frequently accessed time ranges, Certexi pre-computes state snapshots at regular intervals (hourly). Reconstruction then starts from the nearest snapshot rather than replaying from the beginning.
