What is cmAlmLastChange?

This read-only TimeStamp is a snapshot of sysUpTime taken the last time the alarm situation on the node changed (a raise or a clear), and it resets to zero when the agent initializes. An admin cares because it lets them gauge how long ago the last alarm transition happened, a quick indicator of alarm stability on the device. For example, if cmAlmLastChange hasn't moved in weeks, the device's alarm state has been stable since then, while a very recent value flags a just-occurred raise or clear worth investigating.
