You must have created at least one consumer before you can modify a time interval for a resource plan.
You must be a cluster administrator to manage time intervals.
Time intervals allow you to vary your resource plan according to the clock time of the day. For example, you may want to alter your distribution of resources overnight or in the evenings or both.
Time-based configuration in the resource plan allows the resource distribution for a consumer to change according to the time of day.
Time intervals exist across resource groups throughout the tree. No time gaps are allowed in the resource plan.
