Yes, correct. Apple is pretty much fragmented, in fact I would say screwed up when it comes to defining date formats especially on iOS devices. Macs somehow are manageable. For some reasons Apple thinks vast majority of people around the globe would follow Month day and year format.
Canada's official date format is day month and year whether you use short style with hypens or long format without any hypens. For example (dd mmmm yyyy; dd mmm yyyy, dd-mmm-yy, dd-mmm-yyyy) etc. Pretty much same as the UK/Europe/Australia/New Zealand).
In Canada, take any federal and mostly provincial document, your passport or any federal government documents. Driver's licence is your provincial document and they mostly follow yyyy-mm-dd or dd mmm yyyy (in Alberta)
On my iPad in order to obtain dd mmmm yyyy or dd/mm/yy, I have my region setup to the UK and language to British English. If I select my region to Canada, it will put the comma after month (dd mmmm, yyyy), which I don't want.
Apple should give users the flexibility to set the date format regardless of the region they have selected. Even if I am living in the US, I should be able to set the date format to they way I prefer.
For example, in Aperture, no matter what you do you are stick with importing your images with MMM dd yyyy format. You can not change that regardless what format you have setup on your Mac. I then manually change the imported folders name to either yyyy-mm-dd or dd-mm-yy (that I mostly use).
Working the the Numbers spreadsheet on Mac and iPad always screw up my spreadshets and it's really hard to work on this way and keep changing the formatting everytime you transfer your document.
