You are looking for the departure time of your plane at the airport in france, what would the time look like?

Bonjout

What  would the time be ?

In France, the time would be 21:15

is pronounced = vingt-et-une heure quinze

9:15 pm isn't used in France

9:15 and neuf heures et quart Would be in the morning

9:15 du soir isn't correct, 21h is du soir .. so no need to add it

For the hours past noon, we say, treize heure, quatorze heures, etc vingt heure , vingt-et-une heure etc

Hope this helped :)
