With Release Sharing you can choose when
the release is available to the specified label's release creators. Set
the date and time using the available controls. By default, it is set to
the nearest date and time.
Embargo date and time is an option for when you want the release to be made unavailable to other label's creators after a certain window is past. To enable the control, check the circle beside Embargo Date and Time and then use the date and time control.
Enter a future date and time.
