Defining a time frame for blackout policies
Create a time frame to specify the time period for the blackout policy to be active.
Best practice
- Do not create a time frame that a blackout policy might never use. For example, a time frame that covers a complete day, that is "24x7", will never be used because a blackout policy will not be applied all the time.
- Do not create overlapping time frames to avoid confusion.
- Include an abbreviation for the time frame in its name. For example, a time frame that starts at midnight on Friday and ends at midnight on Sunday can be named “Weekends.” If a time frame is related to a specific maintenance period for a specific application, include an abbreviation of the application name in the name as well as a representation of the actual time period for the time frame.
- Provide a description for each time frame and specify the information with maximum impact at the beginning of the description. For example, 31 Oct - Windows upgrade.
Time frame properties

End Time/Duration | End time or duration for the time frame. You have the following options:
Important: Time frames based on start and end times cannot span across midnight. Hence, in this case, you must specify the duration. For example, if you want a weekly time frame that starts at 6:00 P.M. on Saturday night and ends at 6:00 A.M. Sunday morning, create a time frame with the following properties: Recurrence Pattern: Weekly (Saturday) Start Time:18:00 Duration: 12:00 |
