What happens if 2 people get the same time in qualifying formula 1?

In the event two or more drivers set the exact fastest lap in qualifying, the driver who set the lap first gets the pole position. At the 1997 European Grand Prix, Jacques Villeneuve, Michael Schumacher and Heinz-Harold Frentzen all set a lap time of 1:21.072 and the eventual World Champion, Villeneuve was awarded the pole position due to the rule.
