To clarify; from one of my UbuntuMATE 20.04 systems,

Sat Jun 13 05:23:03 bret at bret-Linux-Aspire-5750G:~$PS1="\d \t \u@\h:\w$"
Sat Jun 13 05:23:09 bret at bret-Linux-Aspire-5750G:~$date
Sat 13 Jun 2020 05:23:14 AWST
Sat Jun 13 05:23:14 bret at bret-Linux-Aspire-5750G:~$

shows how the date is formatted differently, with the PS1 parameter of
\n , not using the locale date format, but,rather, using the USA date
format.
