John, I’ll try with that!
Etienne, i use to compile openwrt, in the next compilation I'll try that
nanoseconds support.
Thanks both for your answers.
Best regards

Hi
if you know how to compile openwrt yourself, you can activate nanoseconds
support for date command in:
Base system / busybox / coreutils / Support %[num]N nanosecond format specifier
BUSYBOX_CONFIG_FEATURE_DATE_NANO is in trunk since
https://dev.openwrt.org/changeset/22665/trunk/package/busybox/config/coreutils/Config.in
/proc/uptime is a good trick, thanks for this one

If you want to do multiple commands with time, either put them in a script and
time the script, or do something like:
echo "command 1 ; command 2" | time sh

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
Gabriel

/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
