While a full featured NTPserveror -client reaches a very high level of accuracy and avoids abrupt timesteps as much as possible by using different mathematical and statistical methods and smooth clock speed adjustments, SNTP can only be recommended for simple applications, where the requirements for...
protocol Computer clock for synchronous Internet. When there is no need to implement the NTP complete functionality described in RFC 1305, You can use SNTP. It can be operated in a single broadcast mode (point-to-point) and broadcast (point-to-point). It can also be in IP multicast mode...
The threshold, in minutes, between the NTP or SNTP server time and the local clock time. When the difference is above this value, the local clock will not be set/adjusted. *SAME The maximum adjustment does not change if it was previously set. ...
Calculating our instantaneous offset from the NTP time reference with this data isn't really possible. What we can do, however, is look at how the t value changes over time. The difference between a new t value and the previous t value will tell us how much our local concept of time ...
If the difference between the SNTP server time and the local system time is larger, the update is ignored unless the system clock is presumed incorrect. This is ignored in server-only mode. ServerRole : REG_DWORD Default set to zero (0). Specifies the time server role. If this value is...

Ports Both SNTP and NTP are clients of the User Datagram Protocol (UDP). The UDP port number assigned to NTP is 123. See Also Reference xxx_IOControl (Servicesd.exe) Other Resources Simple Network Time Protocol (SNTP)
The following is sample output from the debug sntp adjust command when an offset to the time reported by the configured NTP server is calculated. The offset indicates the difference between the router time and the actual time (as kept by the server) and is displayed in milliseconds. The clock...
