Currently, uinput doesn't use the input_set_timestamp API, so any event injected using uinput is not accurately timestamped in terms of measuring when the actual event happened. Hence, call the input_set_timestamp API from uinput in order to provide a more accurate sense of time for the event. Propagate only the timestamps which are a) positive, b) within a pre-defined offset (10 secs) from the current time, and c) not in the future.
