After some hesitating, pondering and deliberating (http://forums.macrumors.com/showthread.php?t=1820979), I bought a maxed out MBA 13 inch. It arrived one week ago but I didn't have the time to unbox it until yesterday. While I have not transferred any software or files (I am intending to do a clean install, instead of TM migration), what I find peculiar is that the computer clock is 5 minutes faster than it should be. I already checked "Set date and time automatically" (tried different servers), as well as having checked "Set time zone automatically using current location". MBA is connected to WIFI and Macbook correctly pinpoints my location. Still, the clock is precisely 5 minutes faster than it should be. I have re-started the computer a couple of times. Still, 5 minutes fast. I don't want to solve the problem by just manually setting the time. It should not be this way, not for a new MBA. A quick googling does not show that many other recent Macbook users have the same problem. There is some suggestion that incorrect time is caused by an in-built battery (hardware problem). I would hate to think that this new MBA is defective in any way, and I hope it is just some software quirks that I have not figured out. If so, then what would it be? Any ideas from the experts here? Thanks!!!
