Public bug reported:
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.
