I can see the Aired Date and the dates in the EPG in proper format in my language.
Which means there are strings in the translation project which can be reformatted.
Unfortunately I am not a member of the EN-UK translation team, so I cannot change them myself.
I can merely point any members of that project to some string numbers:
2370, 2371 and 2394–2397 in the ‘Web Clients’ project https://www.transifex.com/plex-1/plex-web/dashboard/
The above link is for the Plex web app and all the smart TV apps and Plex Media Player.
There might be similar strings in other translation projects for other Plex clients types.
