While I'm not objecting to this patch in principle, I find it quite 
unusual that Apple would place a word with the same arguments in the 
global namespace. In particular, I see references like this which 
suggest it is not required:

Can you give some more context as to why the get-time word in the rtc 
node cannot be used?
