The GigE Vision (GEV) timestamp value feature lets you get the latched timestamp value. Because the value is 64 bits, the camera stores it in the registers for the GevTimestampValueHigh and GevTimestampValueLow nodes.
If the camera is in precision time protocol (PTP) mode, this is the PTP clock in the camera.

You can use the eSDK API functions to get the node’s current value.
