Hi,
I'm using TP-Link WR741ND routers with openwrt, and I want to log some
debug files, to know for example how many packets have been transmitted
in a period of time. For that purpose I use while loops and log the
results. The problem is that I couldn't find how to use a good time
reference to measure the time periods. In a PC I can use the date
command with nanoseconds resolution, but in openwrt it seems that it's
not possible to get more resolution than 1 second, at least with the
date command. I'd like to know if there's a way to get a resolution of
at least milliseconds in user space. I've read in some posts that the
problem with routers is that most of them don't have RTCs, but with
ticks relative to processor's clock i'd be OK. I've also read here:
https://forum.openwrt.org/viewtopic.php?id=21965
people recommending to write a specific timer function, but i wanted to
be sure that there's no a simple way.
Regards
Gabriel
