What do you mean the time on my computer is going out of whack?
He means, what is the time set in your operating system? When you send shares back to your pool, it goes back with a time stamp on them. If the time stamp doesnt match up, it gets rejected. Many times with people saying that all their shares are being rejected, its because the time on their OS is not set correctly (few hours off, few years, wrong month, etc).
