I have recently noticed that in the gnome-system-monitor if I go into the settings and tick the box for "Started" in the "Information fields" section of that the "Processes" tab that the "Started" column is not added and in fact this information is not seemingly displayed anywhere except for in the "Properties" window for a process. But it would be really useful if it did actually appear as a column so that you could easily view the start times for multiple processes at the same time and to also sort them in terms of that. I am running Ubuntu GNOME 15.10 with GNOME 3.18 but I have also experienced the behaviour on Ubuntu GNOME 16.04 with GNOME 3.20, in fact when running it on that system through Terminal this was the output (the exact moment I checked the "Started" box in the settings to add that column I got the first bit of output and then very quickly the other output followed):
(gnome-system-monitor:2252): GLib-CRITICAL **: Source ID 73 was not found when attempting to remove it
