Hi,
Generally, no -- that amount of time does not matter. Your score is based on number of questions answered (answer them all!), number of correct answers, and difficulty level. The difficulty level of each question is pre-assigned by GMAC. That is, if you should receive a 37-level question based on your performance so far, the computer will select a question from the 37-level bin.
The early questions are more important than the later questions. So, you should go more slowly and carefully early on to ensure you don't make careless errors (in math and verbal). As you progress, you may increase speed a bit, picking battles and making some educated guesses along the way.
Although the final questions are less important than the early questions, there is a meaningful penalty if you don't finish the section in time. So, keep your eye on the clock and make sure you get to the end -- but not by rushing at the beginning.
Finally, we are hearing about the GRE (not the GMAT) that they are tinkering with the computer model to notice when people click through a few questions at the end to beat the clock. For this reason, we are suggesting that people bake in a few extra moments at the end so let the computer "see" them working on questions. While this is a GRE-issue, given that caution is the better part of valor, I suggest GMATers do the saame.
