I wasn't able to beat the time limit with Impossible AI with the default maps. You could try downloading a smaller one. Targa's "Clash of the Titans" map is a one-on-one map with no sea races allowed. I think it's still available on the Illwinter site. I did manage to beat every nation on Impossible AI with that map. I had way too much time on my hands while waiting for my copy of the game.
