Hello,

Could someone explain the arrangement of the NSEarlierTimeDesignations 
and NSLaterTimeDesignations arrays. In the default Englsh file the 
Earlier array has four entries and the Later array has one. does each 
entry have a special designation? or are they just a random collection 
of related words? Can the arrays have less or more elements? The only 
program I've seen that uses these arrays is GNUMail and it does so by 
numbered elements. Are there any standard methods that use specific 
elements of these arrays? Is there some documentation for the keys in 
this file anywhere?

Thanks
Rob
