include librt alternative in OSX using

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compile in OS X

What is the expected output? What do you see instead?
OSX does not have linux librt libraries, needs to instead use 
mach_absolute_time()

Please provide any additional information below.
Boilerplate solution to clock_gettime  is attached. Still needs _settime, 
_nanosleep and _getres.
