To fully utilize the BT polling/refresh rate, a few input events are sent together to reduce event delay. This causes issue to the timestamp generated by input_sync since all the events in the same packet would pretty much have the same timestamp. This patch inserts time interval to the events by averaging the total time used for sending the packet. This decision was mainly based on observing the actual time interval between each BT polling. The interval doesn't seem to be constant, due to the network and system environment. So, using solutions other than averaging doesn't end up with valid timestamps.
