[LinuxBIOS] Is there sched_clock equivalent in LB?

[Eric Poulsen]

I was going to hack LB a bit, and add a timestamp, just like you see in 
the newer Linux kernels, to look for potential bottlenecks specific to 
my MLB. The kernel printk uses sched_clock() to get the current time.  
Is there an equivalent call in LB?  I've looked through the code base 
for files / code that has *clock* or *time* or something similar, but 
without much luck.
