This reports the exact local date and time of the most recent HA switchover event on this appliance, giving an admin a precise timestamp to correlate against other logs, alerts, or user-reported issues from around that same time. Because it uses DateAndTime rather than a relative uptime value, it remains meaningful even across reboots and doesn't require the admin to do any uptime arithmetic to figure out when the event happened. For example, an admin investigating a brief service disruption reported by users at 3:14 PM would check this object to see if it matches that time, confirming a switchover was the cause.
