Thank you for your answers!
I've tried with the time command, but I couldn't use it for various
commands together as in my pc using parentheses like
time (command 1; command 2)
with date +%s I get a seconds count:
root@E10:~# while true; do date; date +%s; sleep 1; done

Regarding /proc/uptime, I didn't know about it, I think will be enough
for what I wanted!
Best regards

/proc/uptime is much simplier :-)
and it's even monotonic...and...fast.
(date +%s can jump into future and past)
read t1 trash </proc/uptime
do_something()
read t2 trash </proc/uptime
