The ls/abmon-align test does not work today (May 29th) because of the added
check. The problem is that:
touch '-d+N month' for N={01..12}
... in general does not create 12 files with timestamps in different months.
If you run it today (May 29th), touch '-d+09 month' results in March 1st while
touch '-d+10 month' results in March 29th. Consequently, both 09.ts and 10.ts
have the same month (March) to begin with and the check for duplicates has to
fail:
++ echo 'Jun
Jul
Aug
Sep
Oct
Nov
Dec
Jan
Mar
Mar
Apr
May'
++ sort
++ uniq -d
++ wc -l
+ n_dupes=1
+ test 1 = 1
+ test 1 = 0
+ fail=1
+ break 2
+ test 1 = 1
+ echo 'misalignment or ambiguous output in C locale:'
misalignment or ambiguous output in C locale:
+ LC_ALL=C
+ TIME_STYLE=+%b
+ ls -lgG 01.ts 02.ts 03.ts 04.ts 05.ts 06.ts 07.ts 08.ts 09.ts 10.ts 11.ts
12.ts

That was a latent issue with the original test, which I've
now pushed a fix for at:
https://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=c8eb21c
I've a local prototype to address the more general gotcha here
wrt relative date adjustments, which I hope to push soon.
thanks!
