why doesn't htop display the same process start time than ps
Ubuntu 16.0.4.5, htop 2.0.1 and 2.2.0 compiled from source.
Showing the STARTTIME column in htop, displays Jan25 but ps -o lstart displays Sat Dec 15 20:58:46 2018
By looking at the pid it seems that ps's output is incorrect, but htop's not.
