This is not the uptime of the program. It is the uptime of the program since scollector has been running. I don't see the value of this metric, since one can always just subtract the start time and a timestamp to figure out uptime.

Nope, I'm wrong. timestamp is updated to be now. But use now() to get it because it's race-free.

Just use now() for this:

Calculate process start time and uptime from file stat data of /proc/ directory.
P.S. Chose this because it's way simpler than querying uptime,
getconf CLK_TCK, parsing stat and jiffies. There were times when/proc/<pid>stat data was modifiable but that's fixed now.
