Syslinux - Sep 2010 - timestamp in COM32 module

Hello,
I am writing a simple module for measuring boot time. I would like to 
get a timestamp when syslinux is run and then pass it as kernel 
parameter and work with the timestamp later..

It seems that POXIS time.h functions are not implemented yet(?) in 
COMBOOT. I was reading this

http://www.linuxfordevices.com/c/a/Linux-For-Devices-Articles/Benchmarking-boot-latency-on-x86/

earlier today and it sounds good, but I would be really better off with 
seconds since beginning of epoch, plus I am not sure how the TSC count 
behaves on multicore.

Is there some other way to get (some kind of) timestamp in COM32 
environment besides RDTSC?

Best Regards,
Tomas Karasek

it exactly returning. it doesn't seems like what POSIX time() returns.

Also, I was reading this

- Is there some other way to get (some kind of) timestamp in COM32 
environment besides RDTSC and times.c?

- Is there a way how to get a timestamp relative to times() when Linux 
is runnig? I.e. build a static binary that will get times() and run it 
from init?
