I am having a problem with my hackintosh, it won't keep time. I've got it set to automatically update the time, but it only seems to do that when I restart the computer, or open the time and date settings. This machine gets left on 24x7, for weeks at a time, so by the end of 3 or 4 weeks it's out by 20 min or more. I've checked the clock in my bios, and it's dead on, and I've trie4d disabling the auto update, even tried different time servers but nothing seems to work. My macbook seems to be ok though... Any ideas?
