Could you please give a detailed explanation of why this needs to go in an 
installed header, as opposed to purely in a glibc-internal header?  (All 
bits/ headers should be installed headers; the set of installed headers is 
determined by the "headers" settings in makefiles.  Since you're not 
actually including this from the public time.h in this patch, only the 
internal one, there doesn't seem to be a reason here for either the naming 
or installing the header.)
