### Network Time Protocol

Although Network Time Protocol (NTP) is not an essential component of the High Availability server cluster, NTP allows the two servers to have identical times. Having identical times helps when analyzing log files and prevents problems with the RSYNC process.

The Network Time Protocol Daemon (NTPD) is installed as standard for Linux, but is not usually enabled. After suitable configuration, enable and configure the NTPD service to start automatically following a Linux restart.
