Systems and methods for gathering research data using multiple monitoring devices are provided. An example method includes accessing, at a first monitoring device and a second monitoring device, first timing data produced by an external source, the first monitoring device located remotely from the second monitoring device. The example method additionally includes adjusting second timing data generated by the first monitoring device based on the first timing data and adjusting third timing data generated by the second monitoring device based on the first timing data. The example method also includes accessing, at a processing facility, the first timing data and adjusting fourth timing data generated by the processing facility based on the first timing data.
