Abstract: Highlights•Time-synchronization system for evaluating IoT systems and distributed IoT protocols•Low-cost time-synchronized GPIO tracing for IoT testbeds requiring no custom hardware•A single time-source can synchronize a building-wide IoT testbed•GPS-enabled time sources achieve time-synchronization in large testbed deployments•Microsecond time-synchronization accuracy is achievable in any testbed deployment
