Reports the local time on the SSG box when the peak authorization rate in cssgTalMaxAuthRate was recorded. This timestamp turns a bare peak number into something actionable — it lets an admin correlate the peak with a known event, such as a marketing promotion or an outage-driven reconnect storm, instead of just knowing that some burst happened at some unknown point since the last reset. If cssgTalMaxAuthRateTimestamp reads shortly after a mass Wi-Fi outage was fixed, that correlation explains the peak as a reconnect storm rather than an attack.
