/**
 As Apple said [NSDateFormatter init] is very expensive (https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/DataFormatting/Articles/dfDateFormatting10_4.html#//apple_ref/doc/uid/TP40002369-SW10)
 In Apple's code is used a static const, but since NSDateFormatter 
 isn't thread safe a better approach is to use Thread local store (http://developer.apple.com/library/ios/#documentation/Cocoa/Conceptual/Multithreading/CreatingThreads/CreatingThreads.html#//apple_ref/doc/uid/10000057i-CH15-SW4)
 to cache the NSDateFormatter instance
