Hello every one !
I have some difficulties to find how to modify the format string of the duration field.
When i'm editing the list view layout, i insert the field "duration of the event" and it shows like this in front end : Durée de l'événement : 0 Jours 03 heures 00 minutes
I want to modify it in 03:00
How i can do that ? I search in the language file and pretty much everywhere, i don't see how to do it.

Thanks for your help
