When dispatch clocks disagree, the trip record stops making sense

Choose an authoritative time source

Document which system supplies the official operational time. The standard may be a network-synchronized server, dispatch platform, or another controlled source, but staff should know which clock wins when displays disagree.

Include the time zone and daylight-saving handling in the written rule. A timestamp without that context can become ambiguous when records are exported or reviewed later.

Inventory every clock that creates evidence

List dispatch workstations, vehicle tablets, GPS feeds, radios, phone systems, cameras, facility clocks, and paper forms. Note whether each device synchronizes automatically and who owns corrections.

Test the systems together rather than checking them in isolation. A clock that looks reasonable can still be several minutes away from the standard used by another record.

Create a short verification routine

Add a timestamp check at the start of a shift or another defined interval. Record the difference, correction, and person completing the check when a system cannot synchronize automatically.

• Official time source and time zone.
• Systems checked and observed difference.
• Correction method and responsible role.
• Escalation threshold for repeated drift.

Preserve the original record during review

Do not silently rewrite historical timestamps to make them line up. Keep the original values and document any known offset so reviewers can reconstruct the event sequence transparently.
