Usually just us.pool.ntp.org is good enough. Unless your obsessive like me and list, 0,1,2 and 3.us.pool.ntp.org ++1 on http://www.pool.ntp.org/ -- great redundancy and you don't end up hard coding time servers that may go away or drop their public access. If you don't have your own cesium clock it's a cheap replacement .
