NTP is stand for Network Time Protocol. It is used for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. NTP uses UDP on port 123 as its transport layer.
Keeping the date/time synchronized throughout all computers / servers is really necessary. Solaris already comes with the ntp daemon, called “xntpd”.
