What is SNTP?

The Simple Network Time Protocol is used for the synchronization of time and date information from a time server. Some time servers are just a standard PC server and returns the time from its local clock, other time servers are much more accurate and they return the time from an Atomic Clock or a highly accurate radio frequency clock. SNTP uses the UDP transmission method and sends a packet request to the server. The server then responds with a specially formatted data packet that contains the time information as well as some information that allows for the calculation of the packet delay so that a more accurate reading can be made. When a packet is sent over the Internet, the target recipient does not instantly receive the data. There is a latency time for the send and receive process and this needs to be calculated so that it can be applied to the time returned by the server, otherwise the data would be incorrect. The protocol also specifies that the returned time is sent in UTC or U

SNTP (Simple Network Time Protocol) is basically also NTP, but lacks some internal algorithms that are not needed for all types of servers. See Q: 9.4. for more and detailed information. As a full implementation of the NTP protocol seemed too complicated for many systems, a simplified version of the protocol, namely SNTP had been defined.

SNTP is an acronym that stands for Simple Network Time Protocol. As its name suggests, it is a less complicated version of Network Time Protocol, which is a system for synchronizing the clocks of networked computer systems, primarily when data transfer is handled via the Internet. NTP, one of the oldest Internet protocols still in use, uses as its base a GPS clock or other type of radio clock, which can be scientifically accurate to a number of places past the traditional second in a timescale. We don’t necessarily need to keep such precise time in our everyday lives. Computers, however, need to implement very precise timekeeping. Especially computers that are networked together and, therefore, amenable to real-time data sharing need precise timekeeping in order to avoid run-time errors and data corruption. Two computers with time clocks that are just a fraction of a second off can be in for catastrophic data transfer failures. Another reason to synchronize timekeeping for computers is

SNTP is the abbreviation of Simple Network Time Protocol that is used to synchronize the clocks of networked computer system during data transfer via internet. SNTP is the less complicated version of NTP (Network Time Protocol) used for less heavy data transfer and small number of calculation and workstation. Usually computer implement very accurate timekeeping. For this it uses GPS clock or other type of radio clock that is very useful in scientific calculation. The basic function of SNTP is to match the timing of user’s computer according to Internet Standard. This system is suitable for less complicated network system. If there are very few margins even a microsecond difference between the two computers in the network, there will be no data transfer due to data corruption and run-time errors. So it is the basic requirement to match absolute timing of all the system within the network. The another advantage to synchronize timekeeping of the computer appears when any user sends any ma

The Simple Network Time Protocol (SNTP) is a protocol synchronizing multiple systems’ clocks over packet-switched, variable-latency data networks. SNTP uses UDP port 37 as its transport layer. It is closely related to the Network Time Protocol, but simpler.
