A proxy server is a great way to protect your data and keep your online activiti...NTP implements a hierarchical architecture. Each level in the hierarchy is known as a stratum. At the very top are hardware reference clocks, such as GPS or radio time receivers, known as stratum 0 hardware clocks. Stratum 1 NTP servers have a direct connection to a hardware clock and therefore have the most accurate time.The stratum 1 NTP servers are the most precise time servers because their time is referenced to an authoritative time source, like an atomic clock. Stratum 1 NTP servers work as the primary NTP servers. This is because NTP servers in stratum 2 synchronize their time using stratum 1 NTP servers as a reference. To use this specific pool zone, add the following to your ntp.conf file: server 0.au.pool.ntp.org server 1.au.pool.ntp.org server 2.au.pool.ntp.org server 3.au.pool.ntp.org.
