NEW YORK — NBC says Ryan Seacrest will host “The Million Second Quiz,” a new live game show the network hopes will become event programming for two weeks in September.

The network said today it is constructing a giant hourglass-shaped structure in Manhattan for the game, which will involve contestants testing their trivia skills over a million seconds, or 11 days, 13 hours, 46 minutes and 40 seconds. A contestant leading the game earns $10 per second for sitting in the “money chair,” with a potential payoff of millions of dollars.

The show will air for six straight nights starting Sept. 9, then return for four nights starting Sept. 16.

Seacrest is host of “American Idol” on Fox and “New Year’s Rockin’ Eve” on ABC.
