Timestamps are boring until they break your incident review: mismatched clocks can turn a simple outage into days of finger‑pointing, lost evidence, and delayed remediation. In this 10‑minute interview host Alex Morgan and guest Michael Harrington explain why consistent time matters across access control, cameras, alarms, HVAC schedules, and monitoring—without getting into protocol minutiae. We open with an anonymized vignette where misaligned logs delayed a vendor response and prolonged tenant disruption. The conversation then lays out a governance-first playbook: what to inventory (systems that matter), simple acceptance tests to validate cross‑system alignment, who owns time policies in mixed vendor environments, and lightweight monitoring and maintenance cadences to detect drift. Listeners leave with three immediate actions and a downloadable one‑page Time Sync Checklist on the Built, Wired & Secured resource hub. Practical, vendor‑neutral, and focused on decision-making and evidence standards rather than engineering how‑tos.
