regional settings are far too restrictive

[sds]

Settings --> Region & Language --> Formats

Allows me to select the country, not set the actual format.us
I live in the US, so this means that I am stuck with

date: mm/dd/yyyy
time: HH:MM:SS AM/PM
date&time: the weird format which somehow starts with week and ends with am/pm
numbers: 123,456,789.00
measurements: imperial
paper: us letter

basically, since all paper is always "letter", no other country selection will work for me.
however, I don't see why I have to be stuck with the US customary units (https://en.wikipedia.org/wiki/United_States_customary_units - not "imperial") and "infix" date/time formats.

I could set date and time formats to ISO 8601 for the last 10 years at least, and still can do it on Mac.
This appears to be a regression.

As a workaround, why don't you try Canada (English) ?
It uses the US Letter paper size, metric measurement, and the date format is at least closer to what you were wanting.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Want to mention another workaround. Keep US in the UI, open ~/.profile for editing, and add this line:

export LC_TIME=en_DK.UTF-8

And no, it's not a regression. Ubuntu (or GNOME) has never had a more fine tuned GUI for setting regional formats.

Status changed to 'Confirmed' because the bug affects multiple users.
