IIRC, the GPS clock is considered stratum 1, and your sever stratum 2. See for example http://www.truetime.com Inexpensive hand-held GPS receivers can be use for this, too, but are less accurate due to serial communications and you may have problems with signal strength unless you use a remote antenna. They do have the added advantage of being able to clip them onto your dash board, handlebar, or cabin roof for those times when you don't care if your network is getting the absolute correct time or not. ;^) -- "Where am I, and what am I doing in this handbasket?"
