There are two ways you can set a future publish date and time of an article.
When publishing to GNWeb
•Select a future publishing in the menu
On the File menu, point to Publish, and then click Scheduled Publish...
In the form, select the publishing date and time.
•If you cannot find Scheduled Publish... in the menu
Add to the menu the entry:
<l:ShellMenuItem
Header="Scheduled publish..."
CommandParameter="ExecuteWorkflowOnObjects"
Parameters="wf=publish&pars=action:publish;title:Scheduled publish;prompt:true;promptMode:true;isScheduled:true;promptScheduleTime:true;"
/>
And the workflow dialog will show the datetime picker.
The publish task will be saved in the tasktable, and the Back4 will execute the publishing only at the specified time.
•An alternative
An alternative is to publish as usual, and pass to Kentico an attribute that specify the time and date the article will be visible. This option requires implementing a custom dialog in Ted/Fred to select the publish datetime, save this value in the article attributes, and use it at the time of publishing.
When publishing with VirtualCom
In PubAfter enter the date and time when this content is to be published.
