The dates visible in XBert depend on your Region settings in your XBert User Settings.
To change the date format
Click on your image or Profile Settings in the main menu on the lower left of your screen.
โSelect Profile.
โSelect the region you wish to use from the drop-down menu.
Note: Sometimes, the date format defaults to US (mm/dd/yyyy), even though your settings says the default is AU (dd/mm/yyyy). This is because your browser incorrectly installs with the US region.
To fix this, you can manually change the Region to English (Australia).
Once you hit Update, the date format should automatically change to dd/mm/yyyy.
