Specifies a time dependency. If the at keyword is used, then the job or job stream cannot start before the time set with this keyword.


at time [timezone|tz tzname][+n day[s]]


Specifies a time of day. Possible values can range from 0000 to 2359.
Specifies the time zone to be used when computing the start time. See Managing time zones for time zone names. The default is the time zone of the workstation on which the job or job stream is launched.
Note: If an at time and an until or deadline time are specified, the time zones must be the same.
Specifies an offset in days from the scheduled start date and time.


If an at time is not specified for a job or job stream, its launch time is determined by its dependencies and priority and its position in the preproduction plan is determined by the value assigned to the schedtime keyword. For more information about the schedtime keyword refer to schedtime.

If the run cycle and job stream start times are both defined, the run cycle start time takes precedence when the job stream is scheduled with JNextPlan. When the job stream is launched with the submit command, the run cycle start time is not used.

The time value in the at option is considered as follows:
  • If the time value is less than the value set in the startOfDay global option, it is taken to be for the following day.
  • If the time value is greater than the value set in the startOfDay global option, it is taken to be for the current day.

If neither the at nor the schedtime keywords are specified in the job stream definition then, by default, the job or job stream instance is positioned in the plan at the time specified in the startOfDay global option.
