It would be the appropriate separator(s) for the locale in use, not necessarily 
the comma, but I'm guessing that's what you meant.

Personally I think it's a bit more than a bit weird to have "Year: 2,014". It 
seems pretty ugly to me, and four digit years are going to be the common case.

I wonder if it would be that bad to have a 'year' type to compliment the 'month' 
and 'day' types...
