Public NTP Servers

Online NTP servers are available as a source of atomic time or UTC (Coordinated Universal Time). The UK internet time servers listed on this page are taken from pool.ntp.org and were correct on 2019-10-22.

However, the time derived from internet time sources may be innacurate and it requires you to breach your firewall in order to obtain the signal, potentially giving hackers and or viruses entry to your network!

The only secure and accurate method of synchronising the correct time across a computer network is to use a dedicated NTP server. These devices receive an external atomic clock time signal often by GPS or even by radio transmissions and sit safely behind your firewall!

But, if we still haven't convinced you that a Galleon Systems dedicated network time server is the best choice - here are the lists of stratum 1 and stratum 2 NTP servers available on the internet:
