Show Message at specific timestamp

is it possible to show a M开发者_运维知识库essage at a specifict timestamp even if the app is in background.

On the iPhone there are LocalNotificaitons to handle this.

This is not possible with the current framework. However, the upcoming Mango release will include an Alerts API. The developer tools are due for release next month and the consumer release is expected around November.
