Gamepad.timestamp 特性为 Gamepad interface returns a DOMHighResTimeStamp representing the last time the data for this gamepad was updated.

The idea behind this is to allow developers to determine if the axes and button data have been updated from the hardware. The value must be relative to the navigationStart 属性在 PerformanceTiming interface. Values are monotonically increasing, meaning that they can be compared to determine the ordering of updates, as newer values will always be greater than or equal to older values.

注意 : This property is not currently supported anywhere.

句法
