How do you change the date format in the admin interface? I have changed the primary language to en-GB, but that has no effect, as dates still seem to be in the en-US format.
From what I can see, after changing the culture to en-GB the date is displaying dd/mm/yyyy in form fields, but still in US mm/dd/yyyy in the datagrids.
For 4.3 I personally just changed the "DEFAULT_DATE_FORMAT" to be "EN-GB" format, but it might be worth trying the fix for 4.4 (so it is tested by the time it is released).
As for the need for recompiling the source, that is necessary, given all of the bugfixes and regularity in https://github.com/nopSolutions/nopCommerce/tree/4.30-bug-fixes
Can you explain how to get to the DEFAULT_DATE_FORMAT to change it? I am on my first installation and finding the US-focussed defaults difficult to change!
