Locales are complicated and not my cup of tea ;) Found this: https://superuser.com/questions/1497422/debian-9-vs- debian-10-different-date-output-the-same-locale-the-same-timezone
Another user noted the same change when going from debian 9 to debian 10. I honestly don't know if this is a bug, or if it's fixing a bug. Since LC_TIME is set to en_US, maybe the new output in focal is fixing a bug, and using the US format? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to coreutils in Ubuntu. https://bugs.launchpad.net/bugs/1858883 Title: date utility format unexpectedly changed after upgrade from bionic to focal Status in coreutils package in Ubuntu: New Bug description: After upgrading my Bionic system to Focal, I noticed a significant change in the output of the `date` utility. This could potentially cause regressions for those who are relying on a consistent date format when using `date` in shell scripts. EXPECTED BEHAVIOR ================= I expected to see the same date format that can be seen on Ubuntu releases (at least) from Trusty through Bionic: $ date -u Wed Jan 8 21:00:14 UTC 2020 ACTUAL BEHAVIOR =============== On Focal (and Eoan) the following date format is seen by default: $ date -u Wed 08 Jan 2020 09:00:14 PM UTC Note the differences in zero-padding, whitespace, placement of the year, and the extraneous "PM" (I had expected to see a 24-hour time). FURTHER DETAILS =============== This machine was originally on Bionic and has been upgraded to development releases between Bionic and Focal. $ locale LANG=en_US.UTF-8 LANGUAGE= LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL= To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/1858883/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
