CLOCK_REALTIME?

[Wolfram Sang]

Greetings everyone :)

I am just porting a driver from RTLinux to RTAI and there is one 
substitution I did, which I am not sure about: The original source 
included "RTL_TIME.H". I couldn't find a similar include within RTAI. 
So, I simply replaced all "hrtime_t" with "RTIME" which only left the 
"CLOCK_REALTIME" undefined when compiling. As I cannot include "time.h" 
because of lots of conflicts, I just added the "#define CLOCK_REALTIME 
0" from it to the driver-source. But I am not sure if this is a good 
solution, as RTLinux defines "CLOCK_REALTIME" by reading some array. So 
my question is, if there is a better way to define it in RTAI?

By the way, this is my first Linux-project, so please forgive me, if my 
questions turns out to be too easy. ;)

Best wishes
