[Request]: AccelerometerEvent doesn't have timestamp

Plugin

Use case

The AccelerometerEvent and UserAccelerometerEvent doesn't have timestamp, and as described in the issue, it's unreliable to measure by stopwatch or datetime. While there's a issue tracking this #80, but it's closed and this is still missing in the latest version, so please consider to add it.

Proposal

Add timestamp for AccelerometerEvent and UserAccelerometerEvent.
