Viertel vier
... German for a quarter past three (time of the day) (externer Link)
In German "viertel vier" and "viertel vor vire" must not be confused. The first version means: a quarter on the way from three to four o'clock, which is either 3.15 or 15.15. The latter means: a quarter still before us on the way from three to four o'clock, which can either mean 3.45 or 15.45.
