Insert Date Timezone is always UTC in French version too

Hello ! We’re having the exact same issue as here Insert Date Timezone is always UTC ; my Timezone is ignored
Same thing : doesn’t work with quotes, works without quotes.

Hi can you give me the raw you try to insert please? And also your locale.

[date=2020-05-12 time=12:00:00 timezone="Europe/Paris"] -> Gives me 14:00

[date=2020-05-12 time=12:00:00 timezone=Europe/Paris] -> Gives me 12:100:

Locale is Français
