joined at (UserTenant.joinedAt) is a field stored on each user tenant record in Chalk, the higher-education academic operations platform for curriculum, assessment, faculty, scheduling, accreditation, and budget. It holds a DateTime value and is part of the user tenant record's data. The joinedAt field belongs to the user tenant it is recorded on, so faculty, staff, and automations read or set joinedAt while working with that UserTenant record. Because joinedAt is part of the UserTenant record, it stays consistent with the rest of that record's data and is scoped to the tenant that owns the user tenant.
