Package: htop
Version: 1.0.3-1
Severity: wishlist
Tags: patch
Dear Maintainer,
It would be nice if htop had the possibility to output the time
elapsed since the start of a process (as ps -o etime does).
Attached is a patch that implements this feature. It is probably not
optimal, but it is a proof of concept that it is possible.
Cheers,
