See, this is the reason why humanity cant progress.
Thinking about it we are ALL wrong... time is an artificial human construct...
If we can't reach an agreed universal standard, in today's modern age why isn't there some simple computer program in every operating system that sees dates and displays them the way an individual prefers. The person who's OS wrote the date could tag it as a certain style when they wrote it so no matter where or how you write it, it would be viewed the way they want to see it, as long as you don't change your style compared to your preference in the OS it shouldn't be that difficult to get universal understanding...
That way while no one is right, everyone is.
