How to change Date Format

Anyone here knew on how to change the date format on this application.
The dfate format is shown as American.
I want to change to suit my region, but couldn’t find where I can do it.
Please share your answers.

Hi, this is not American date, the date format is YYYY-MM-DD

What kind of date format do you need?

Hi, I want to use DD-MM-YYYY format. Is there option to change?!

This option is not available yet, but I have created a user poll to see if other users have similar need: [POLL] Different Date Format
