That's the time the Bluebirds' forecast it will take to complete the development of the new Leckwith soccer complex from 30,000 to 60,000 seats.
Four phases of stadium development are proposed after the initial scheme, with the final 6,000 seats, costing £9m, earmarked for the 2014-15 season.
The overall cost of expansion to maximum capacity is put at £44m, according to details obtained by the Echo.
We can also reveal today full details of what Bluebirds' owner Sam Hammam will have to fund as part of the 69-acre land deal with Cardiff council.
This involves a £21m package of community benefits and improvements which will flow as a result of the development of the stadium.
Gabbidon and Earnshaw - linked to a £5m move to Fulham earlier this month - have been widely tipped to make the jump up to top-flight football sooner rather than later.
Among them are Peterborough boss Barry Fry, who told The Western Mail earlier this week he thought the Cardiff City pair even had the talent to succeed with one of the Premier League giants such as Manchester United or Arsenal.
But, with the January transfer window closing soon, Bluebirds boss Lennie Lawrence said he was not surprised there had been no bids for either of his prize assets.
"Some people don't believe me, but I honestly wasn't expecting any offers to come in," said Lawrence.
Forest have hit the deck hard, finding themselves third from bottom of Division One without a win or a goal in their last six games, and City are expected to take all three points.
It's a far cry from just three weeks back when the vitriol was aimed squarely at Lennie Lawrence and his players, but the manager bristled at the suggestion that the two clubs' situations were anything close to similar.
"I wasn't in anything like Forest's situation and the two things are totally irrelevant to one another," said Lawrence. "I lost a few games which took me to the absolute depths of the first division, when this club hasn't been there for 30 years.
The Bluebirds face strugglers Nottingham Forest and Derby County in their next two games before a hat-trick of massive games against West Brom (a), Sunderland (h) and West Ham (a).
By the end of February, City could know exactly what group of teams they will finish in come May, the play-off pack or the mid-table misses.
That's why Thorne will do his best to take full advantage of any nervous Nottingham Forest defending tomorrow and also because he knows he won't often get the chance to do it.
