You should use UCConvertUTCDateTimeToCFAbsoluteTime() and CFDateCreate().  
Since CFDate is toll-free bridged with NSDate, you can just cast the result.  
(You do have to be mindful of memory-management issues, of course.)

You can also feed the CFAbsoluteTime value to +[NSDate 
dateWithTimeIntervalSinceReferenceDate:], since the reference date is the same 
between the two.
