A temporal attribute used as one dimension of an access control condition, alongside companions such as time of day and point of origin, to scope when a subject is permitted to authenticate or exercise access rights. Organizations may define access privileges or other attributes by account, type of account, or a combination of the two; examples of attributes required for authorizing access include restrictions on time of day, day of week, and point of origin. In practice, restrictions on time-of-day, day-of-week, and point-of-origin are used to define account attributes, with organizations also considering system-related requirements such as scheduled maintenance and mission/business requirements such as time zone differences. The phrase is compositional rather than a fixed term of art: it names a plain calendar concept that serves as an enumerated example of a contextual access-control parameter, not a specially defined construct with a meaning unique to the security field.
