Added clock notifications for elapsed time.

Added notifications to default `clock` module to broadcast:
 - `CLOCK_SECOND` for a clock second, and 
 - `CLOCK_MINUTE` for a clock minute having elapsed.

Each notification is broadcasted with the corresponding value i.e. `CLOCK_SECOND` -> `30` and `CLOCK_MINUTE` -> `5` .
