Get system time

Hello
I have a NFX board with Linux running on. I have to know the the system time passed from the Linux or board comes up. My application is written in C++. C is also applicable.

Thanks, Eli

Would the time(2) systsm call fit the bill? http://man7.org/linux/man-pages/man2/time.2.html.

time(2) as described in Linux manual page you attached

time() returns the time as the number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC).

I'm looking for a boot time that starts when the board or Linux comes up.

clock_gettime(2) with a clock ID of CLOCK_MONOTONIC.
