one trickey way is
U get date and time in init_module where u can access
linux system calls. and record time(nenoseconds) with
gethrtime() also there.
Then whereever u want date and time again read time
with gethrtime and calculate elapsed time from ur
program startup. Then convert these nanooseconds to
seconds and add it to time. The pseudo code look like
this. I hope it will work.
hrtime_t start_time;
ur_real_time_thread()
{
hrtime_t current_time;
hrimte_t elapsed_time;
current_time = gethrtime();
elapsed_time = current_time-start_time;
convert elapsed time to seconds
add these seconds to ur actual date and time
recorded in init_module.
}
init_module()
{
get date and time with linux syscalls;
start_time = gethrtime();
}
