Your pages can be published or taken down automatically by the UBCMS at a predetermined date and time. The UBCMS provides two methods—Delayed Activation vs Scheduling On/Off Time—each with its own pros and cons.
From the Websites view, you can quickly use the toolbar to choose Activate Later or Deactivate Later to preset a specific date/time for a page to be published, or unpublished from your public site.
This option is only available to those with Publisher permissions. For others, it will be grayed out.
You can over-ride the Activate Later / Deactivate Later settings using the standard Activation and Deactivation tools, although the scheduling will remain in place until the preset date and time.
From Page Properties, you can use Scheduling On/Off Time to quickly set a specific date/time range for a page to be displayed on your live website.
This is handy for a page that is embargoed UNTIL a specific date/time, or for a page that must be hidden AFTER a specific date/time. Be careful when adding these constraints to a page that is already activated, or one that may need to be activated before the On/Off scheduling takes effect normally, as they may hide or reveal it unexpectedly on your site.
This option is available to those with Publisher permissions. For others, it will be grayed out.
When a published page is provided with a Schedule On Time, the page may immediately disappear from the published site with a '404 error' until the On Time occurs as scheduled.
If the On/Off Times are in the future, there is no need to activate or re-activate the page. (These settings act as triggers, which activate/deactivate the page as the set time is reached. If the time has already been reached, that trigger action will not occur.)
Subsequent reactivation will send the page changes to the live site, but will not over-ride the set On/Off Times, so the public will not necessarily see those changes.
Do not set Feature Time by mistake. Feature On/Off Time relates to "Scheduling" in list components.
