I'm now running linux 2.6.21 on my custom virtex 4 board modeled after the ml410. The cpu clock is 300MHz and the PLB bus is 175MHz. My question is which clock is the linux system clock that keeps track of the date derived from? I set my date with rdate -s time.mit.edu at boot and then compare with the date command and rdate -p time.mit.edu and they are off by 20 or so seconds even just after a few minutes, this trend continues and it will be off by a day after a few hours. I think I just don't have something defined correctly but I can't figure out which.
