Clock is always off for me. The AI with it tries to win battles by it, and also he cannot bring his full force to bear if the clock is on, when he invades with more than 1stack (that happens often at the lower unit sizes, as there are many stacks around). Also, as many others said, teh clock is ultimately annoying in deciding battles at a point when they should have clearly gone the other way, both when you ought to have lost or ought to have won.
Too many good fights that i won on the edge to remember and list. Too many also that i lost on the edge, equally fun and satisfying despite - or because - of the loss. I feel the game has much more worth, when i lose fair and sqaure after a tough fight, and the total war AI of STW and MTW have surprised me in this way many times. RTW and M2TW - sometimes do, but far less consistently and spectacularly.
