11.4. NTP Server
NTP stands for Network Time Protocol, an Internet standard protocol (built on top of
TCP/IP) that assures accurate synchronization to the millisecond.
The NTP Server represents a server dedicated to time synchronization.
First,
TB
OX
MS
connects to Internet (through an ISP connection) and then to the NTP
Server.
Example with a connection to Windows server through Ethernet
Examples of Servers:
time.windows.com
europe.pool.ntp.org
You will find valuable information, like lists of Servers with open access at:
www.ntp.org
public time server list
The organization pool.ntp.org proposes servers using DNS round robin, which make a
random selection from a pool of open access time servers. This is good enough when
working with TB
OX
MS.
Round Robin DNS technique is used when the number of access to a server is unpredictable,
to balance the use of IP addresses (load balancing technique).
11.4.1. Time accuracy
When setting time, TB
OX
MS takes into account the propagation delay. This is particularly
important when connecting to the server via modem.
The precision is of 1 second.
