nvgstcapture: no exposure-time option

In this link:

https://developer.ridgerun.com/wiki/index.php?title=Gstreamer_pipelines_for_Tegra_X2

nvgstcapture has an option to set the exposure-time. However, on my tx2, nvgstcapture does not have this option.

How can I set the exposure-time?

Below are the options I see on my TX2:

nvgstcapture-1.0 --help

Encoder null, cannot set bitrate!
Encoder Profile = High
Usage:
nvgstcapture-1.0 [OPTION…] Nvidia GStreamer Camera Model Test

Of course, moments after posting this request, I see there is a --help-all which does list the exposere-time option.
