I listened to Minister de Weever yesterday on Island92, and I'm listening to a replay of today's press conference right now. What Prime Minister Jacobs just said (beginning around 26:30 into the replay) is, as has been mentioned by others, very different from what Minister De Weever said.

If I must receive the test results at least 72 hours before travel (Prime Minister Jacobs) then I could get tested today, and travel in July.

If I must receive the test results within 72 hours of travel (Minister de Weever), that makes more sense. I could get tested on Monday, get the results on Thursday, and fly on Saturday or Sunday - but no later than Sunday.

I expect that there will be further clarification.
