Keeping clock in sync

[spoccka]

My Macbook Pro's clock always seems to drift off the real time by about 3 minutes every week. Does anyone have an idea as to how to keep this in sync.

Thanks!

Have you selected "Set date & time automatically" in System Preferences?

I have yeah, it's still off by about 3 minutes. I can change it manually but I'd prefer having the right time...
