I would like to implement a feature that only delivers messages to devices at specific periods. After the valid time, messages would be abandoned. Can anyone suggest me how to do this?

Google just released a new version of c2dm called "Google Cloud Messaging (GCM)" at I/O 2012. With GCM its possible to define a timeout for your messages.
GCM ttl section: http://developer.android.com/guide/google/gcm/adv.html#ttl

C2DM itself doesn't have such a facility so you have two choices:
- Your server app only sends messages during certain times or
- Your Android app receives the C2DM messages all the time, but during certain times you ignore/handle as appropriate.
