This read-only value reports the sysUpTime at which this VC endpoint row was created. Because it's a sysUpTime-based snapshot rather than wall-clock time, it's mainly useful for calculating how long an endpoint has existed relative to now, distinguishing a connection stable for weeks from one just re-created moments ago, such as a flapping soft VC repeatedly tearing down and reconnecting. A soft VC endpoint whose creation time keeps advancing every few minutes on repeated polls is a symptom of the VC repeatedly failing and being re-established rather than staying up.
