AbsoluteToNanoseconds deprecated - so use what instead?

DriverServices.h says:
AbsoluteToNanoseconds(AbsoluteTime absoluteTime)              __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0, __MAC_10_8, __IPHONE_NA, __IPHONE_NA);

So what I am to use instead?

I want to convert differences to calls to mach_absolute_time() into real world data.

Currently using:
uint64_t machTime[...];
...
    machTime[i] = mach_absolute_time(); 
...
uint64_t elapsed = machTime[i] - machTime[i-1];
UnsignedWide  elapsWide = UInt64ToUnsignedWide( elapsed );
Nanoseconds diffWide = AbsoluteToNanoseconds( elapsWide ); // <--- deprecated
UInt64 diffU = UnsignedWideToUInt64( diffWide );

Gerriet.
