The scheduling class of the process. The command with all its arguments as a string. Many processes can be attached to the same lnode. All the processes attached to an lnode are collectively subject to the lnode's memory and process limits. Each lnode is addressed by a unique key which is a UID number.
Some data printed for defunct processes is irrelevant.
When a machine's system time is corrected by timed or timeslave and if the correction sets the time to an earlier value, ps reports a meaningless huge or negative TIME value for the timed or timeslave processes.
