Ntp clock server
An NTP server is a time source, while an NTP client is a system or device that tries to synchronize its clock with a server. Servers can be primary or secondary. A primary server gets UTC time signals from a highly precise source, such as an atomic clock or, more typically, a GPS signal source.Mar 9, 2023 · Warning: Using the free-running system clock means that your NTP server announces that time as reference time to any client, no matter how wrong it is. Especially when connected to the Internet this can cause severe confusion. A survey discovered that about 95% of bad stratum-1 servers had configured LCL, the local clock, as time reference. So ...

An NTP server usually receives its time from an authoritative time source, such as a radio clock or an atomic clock attached to a time server, and then distributes this time across the network. NTP is extremely efficient; no more than one packet per minute is necessary to synchronize two machines to within a millisecond of each other.However, these servers will support authenticated NTP only - not the other time formats and services supported by the other NIST servers. The clocks on these systems will be synchronized using direct, hardwired connections to the NIST ensemble of atomic clocks that are co-located with the servers.sudo timedatectl set-ntp no.
