How do I get Jira to display dates in a format that is understand by anyone other than a Chaotic Evil person?

What's so hard about 2017/12/14?
Completely unambiguous. No internationalisation issues. Globally recognised.
Whereas mm/dd/yy is HEAVILY ambiguous to most people a lot of the time.
132 days out of 365. That's a lot of days where talking to someone who is Chaotic Evil results in confusion. Over a third of the dates in mdy format have a valid dmy view (2/1/17 - 2nd Jan or 1st Feb?)
Please just stop being evil. You are doing the world no favours with this.
Just use Y-m-d and be done with it. Sure, you're going to have grumbles from the Chaotic Evil's of the world, but they are wrong. It is that simple.
