Locales are a beautiful thing, but they also cause many many weird
issues... but it is ever so annoying to see a numeric date and have to
wonder which is months and which is days (for exmaple in Thunderbird),
so I configured my locale to be a wonderful mix of nl_NL and en_US...

I think to switch the locale you would have to do some more work, like
set an environment variable.
