Synced Clock for AR Session

[xlDownxl]

Hello everyone,

I would like to build an app that records frames and depth images throughout an AR session.
For this purpose I need to have the time synchronized as best as possible.

My question is, whether there is a better way to get the ARFrame timestamps synced than to call sync before recording and safe the offset to add it later to the recorded internal timestamps.

Thanks already for your help!
