systemd-timesyncd is a system service that may be used to synchronize the local system clock with a remote Network Time Protocol (NTP) server. The systemd-timesyncd service implements SNTP only. This minimalistic service will step the system clock for large offsets or slowly adjust it for smaller deltas.

Where does the NTP network get its time from?

All NTP communication uses Coordinated Universal Time (UTC), which is the same as Greenwich Mean Time. An NTP network usually gets its time from an authoritative time source, such as a radio clock or an atomic clock that is attached to a time server.

How does NTP synchronize with UTC timescale?

NTP Timescale and Data Formats NTP clients and servers synchronize to the Coordinated Universal Time (UTC) timescale used by national laboratories and disseminated by radio, satellite and telephone modem. This is a global timescale independent of geographic position.

Which is part of the network receives UTC time?

At its most basic, an NTP network is comprised of the devices to be synchronised (known as clients ) and an NTP server , which receives UTC time and provides it to the clients. The clients and server communicate in a series of requests and responses:

Is the NTP server accessible by the client switch?

An NTP server must be accessible by the client switch. NTP uses the User Datagram Protocol (UDP) as its transport protocol. All NTP communication uses Coordinated Universal Time (UTC), which is the same as Greenwich Mean Time.
