Introduction
The Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer
systems over packet-switched, variable-latency data networks. A less complex implementation
of NTP, using the same protocol but without requiring the storage of state over extended periods
of time is known as the
Simple Network Time Protocol
(
SNTP
). NTP provides Coordinated
Universal Time (UTC). No information about time zones or daylight saving time is transmitted;
this information is outside its scope and must be obtained separately.
UDP Port: 123.
Daylight saving
is a period from late spring to early fall when many countries set their clocks
ahead of normal local time by one hour to give more daytime light in the evening.
