United States — us.pool.ntp.org

To use this specific pool zone, add the following to your ntp.conf file:

	   server 0.us.pool.ntp.org
	   server 1.us.pool.ntp.org
	   server 2.us.pool.ntp.org
	   server 3.us.pool.ntp.org

In most cases it's best to use pool.ntp.org to find an NTP server (or 0.pool.ntp.org, 1.pool.ntp.org, etc if you need multiple server names). The system will try finding the closest available servers for you. If you distribute software or equipment that uses NTP, please see our information for vendors.
