However, it looks like usdview does not set time and frame values, or I can't figure out how. They're shown as "ND_time_float" and "ND_frame_float" in usdview.
Select "root/Root" and switch between material variants; "FrameSample", "TimeSample" and "MarbleTime" should to the best of my understanding animate something when the timeline is scrubbed. "Plastic" is provided for reference.
