# timestampNs

`val timestampNs: Long`

Timestamp in nanoseconds at which the video frame was captured from some system monotonic clock. Will be aligned and converted to NTP (Network Time Protocol) within AmazonChimeSDKMedia library, which will then be converted to a system monotonic clock on remote end. May be different on frames emanated from AmazonChimeSDKMedia library.

See DefaultSurfaceTextureCaptureSource for usage of a AmazonChimeSDKMedia library class which can convert to the clock used by the library
