Possible ls locale bug

[gnu . 3bp3s]

Hello,

My locale is en_IE.UTF-8, so when I run the date command, the output at time of 
writing is "Mon 15 Jan 2024 20:39:04 GMT"

Maybe I'm mistaken, but with that in mind I'd expect the following scenario:
With time locale en_IE.UTF-8 the --time-style=locale within the past year 
should be equivalent to --time-style"+%e %b %R". And older than a year would be 
equivalent to --time-style"+%e %b %Y".

However, this is what I get with following command
$ ls -l --time-style=locale
total 12
drwxr-xr-x 2 bjorn bjorn 4096 Aug 23 2022 dir1
drwxr-xr-x 2 bjorn bjorn 4096 Dec 30 17:44 dir2
drwxr-xr-x 2 bjorn bjorn 4096 Jan 15 19:25 dir3

-rw-r--r-- 1 bjorn bjorn 0 Dec 18 12:16 file2
-rw-r--r-- 1 bjorn bjorn 0 Jan 15 19:25 file3

As you can see, even though I specify using my current locale, it outputs date 
as Month before Day.

Is this a locale bug within ls?
