In the last national election, how many days did it take for the EMB to announce certified results?

“The Constitutional Court confirmed the results on 25 July, ruling that Sassou Nguesso had won the election with 78.61% of the vote (1,055,117 votes). Akouala Atipault said that Sassou Nguesso would be sworn in for his new term on 14 August 2009.^”
