This value, typed as an IpAddress though it actually encodes a time, reports when this version of the system description (!RV2) file was dynamically edited, complementing cntRevEditDate. An admin building a precise audit trail of configuration changes would combine this time value with the edit date to pinpoint exactly when the file was last touched. For example, matching cntRevEditTime against a change-management ticket's timestamp would confirm the edit was performed during the approved window.
