Set Up Time-Dependent Publishing
To publish documents on a time-dependent basis, you define for each document its lifetime in the form of a validity period. During the validity period, documents are visible to all users with read permission. Outside of the validity period, documents are visible only to users with write permission.
You have write permission for the folder containing the documents that you want to publish on a time-dependent basis.
...
1. Open the Details dialog box for the folder.
2. Choose Settings ® Lifetime.
3. Choose Enable Time-Dependent Publishing.

These settings are only valid for the current folder. Subordinate folders do not inherit these settings.
...
1. Open the Details dialog box for the document.
2. Choose Settings ® Properties ® Lifetime.
3. Enter a valid-from time and a valid-to time and save your entries.
When the valid-from time is reached, the document is visible for users with read permission. The system notifies subscribed users about the document. As of this time, users can find the document using the search function or by searching in categories.
When the valid-to time is reached, the document is no longer visible for users with read permission, but it still exists. Users with write permission can still see the document.

There can be a time lag with time-dependent publishing.
