Max. value of device timestamp

[houb3]

Hi,

I'm recording the device timestamp from Vive Pro Eye, using SRanipal SDK 1.3.3.0, Unity 2020.3.32f1. Enable eye version is set to version 2. 

The code I used to get this device timep stamp is "eyeData.timestamp"

From the logged data, it seems the device timestamp resets to 0 after the value exceeds some number. The largest number in my file is 4294964. At the next frame, the device timestamp is 5.

I want to recover the timestamps, does anyone know the max. value of at which it resets back to 0?

 

thanks,

James
