Morrison once in an interview said that Clark was 19. He said something like "what 19 year old would want there mom to make a romper suit for them" (this is him talking about Clarks look). But in later interviews he describes Clark as a 20 to 22 year old.
So I think the oldest he has ever been stated to be in Action comics was 22 years old.
So Clark is around 24 to 27 max in the vanilla book (Superman)
I know I'm late to the discussion, but here's my take on how it should be and why Bruce is older that Clark.
Bruce trained and operated in the shadows for years before it turned out Batman wasn't an urban legend; Superman showed up and opened pandora's box, as it were, showing the world that these super-types aren't myth: they're real.
But, hey, what do I know?
A robotic journey toward the American Dream: MADE in USA.
Heck, for all we know, it could later be revealed that Bruce and Clark actually found out about each other within the first month of being 'active' and the 'fight' they had in Justice League issue 2 was a set up...

In the current JL issue Superman and Batman has declared they trust each other and works together frequently while they are wary of other leaguers. Liked that sequence a lot. It may even be a foreshadow of a Superman/Batman book in the FOURTH WAVE.
Damn a weekly digital Superman/Batman book would be awesome in addition to an extra monthly print one. If in continuity the print book would have substantial sale too.
