This is our 2015 moderator election page over at CR.
The results box shows :
This election ended Jul 14 at 20:00.
Now, I appreciate that if you hang around any part of the network, you'll probably become confused by an ambiguous date like this relatively quickly and figure out that it's showing "mm / dd". But it shouldn't be necessary.
I suggest making the default format "MonthName dd yyyy" so as to avoid potential ambiguity, especially for new users.
