Time-of-day and day-of-week checking for users and terminals

z/OS Security Server RACF Security Administrator's Guide
SA23-2289-00

The time and day-of-week checking for users and terminals applies when users log on to terminals from products such as TSO/E, IMS™, CICS®, and NetView® (beginning with Release 2), but does not apply to batch jobs or started tasks.

User verification processing includes the following time/day-of-week checks:
  1. The user's authority to use the specific terminal. If the profile protecting the terminal does not have any time or day-of-week information, the user can log on. If there is time and day-of-week information, RACF® calculates the time-of-day at the location of the terminal from which the user is logging on (if that time is different from the time-of-day at the location of the processor complex), and checks whether the terminal can be used at this time on this day of the week.
  2. The user's authority to access the system. If the user's profile does not have any time or day-of-week information, the user can log on. If there is time and day-of-week information, RACF calculates the time-of-day at the location of the terminal from which the user is logging on (if that time is different from the time-of-day at the location of the processor complex), and checks whether the user can enter the system.
