Ntp clock server - A Stratum 1 Time Server is a network appliance that receives precise time from a hardware reference clock to provide a time resource to client computers. Network Time Protocol (NTP) implements a hierarchical system of time references. The stratum, or hierarchy level, represents the distance of a time server from the source reference clock.

 
The NTP server comes pre-configured with some server pools already, which you can see inside the /etc/ntp.conf file. ... remote – The remote server you wish to synchronize your clock with; refid – The upstream stratum to the remote server. For stratum 1 servers, this will be the stratum 0 source.. Ameritrade thinkorswim

So a reference clock itself appears at stratum 0, while the closest servers are at stratum 1. On the network there is no valid NTP message with stratum 0. A server synchronized to a stratum n server will be running at stratum n + 1. The NTP client initiates a time-request exchange with the NTP server. As a result of this exchange, the client is able to calculate the link delay and its local offset, and adjust its local clock to match the clock at the server’s computer. As a rule, six exchanges over a period of about five to 10 minutes are required to initially set the clock.To synchronize the system clock with NTP servers To synchronize the system clock with a reference clock, for example a GPS receiver To synchronize the system clock with a manual time input As an NTPv4(RFC 5905) server or peer to provide a time service to other computers in the network chrony performs well in a ...Home Guides.
