Meaning
a loose sense of time that allows for turning up very late

une heure approximative
Explanation
Standard French has no name for it beyond une heure approximative. In Senegal and Burkina Faso it takes its name from the franc CFA, and the wait can run long.

Le mariage commence à quinze heures, mais c’est l’heure CFA, donc on verra.
The wedding starts at three, but that's CFA time, so we'll see.
