Using Magento 2.3.1
When admin locale is en_GB it processes dates wrong. For example filtering orders by date. The date pickers work correctly so the 1st May comes out as 1/5/2019 but Magento processes this as if it were an American date, e.g. January 5th
If I change to en_US locale it works consistently but I would like to use en_GB.
How can I fix this?
