Wonderful this did the trick:

~$ ps -eo tid,lstart,etime -q 1620,6841
    TID                  STARTED     ELAPSED
   1620 Mon Nov 20 16:12:47 2023  1-01:33:53
   6841 Tue Nov 21 15:59:36 2023    01:47:05

I guess TID means Thread IDentifier although in the "ps" man page is not 
explicitly mentioned:
...
tid         TID       the unique number representing a dispatchable 
entity (alias lwp, spid).  This value may also appear as: a process ID 
(pid); a process group ID (pgrp); a session ID for the session leader 
(sid); a thread group ID for the thread group leader (tgid); and a tty 
process group ID for the process group leader (tpgid).
...

I'm wrong? What does it mean?
