Issue Description

I'm trying to verify that the clock domain for the accelerometer and gyro are both Global Time. However, with current release, it seems that only the gyro has faltered to System Time:

This error message reports:

Per-frame metadata is not enabled at the OS level!
Please follow the installation guide for the details.

I presume the message is referencing this document:

https://github.com/IntelRealSense/librealsense/blob/master/doc/frame_metadata.md#metadata-support-for-intel-realsense-devices

However, all other metadata streams seem to correctly display a Global Time clock domain:

What could cause this inconsistency? I've been able to replicate the exact issue on two different ubuntu PCs, two different D435i devices, as well as building from source as of 83f952a .

FYI: versions of debian package used:

$ apt list --installed librealsense2*
