The lastUsedAt field on a ApiKey record in Skarn Suite (the platform auth hub: SSO, tenancy, billing, entitlements, internal event bus) stores a specific piece of the data; it records the date and time the event occurred, giving an accurate timeline used for scheduling, audit history, reminders, and operational decisions. In everyday use this is part of how ApiKey records are created, displayed, validated, and reported, and it is grounded strictly in the real schema fact ApiKey.lastUsedAt: DateTime.
