# Configuring SNTP

|  | Simple Network Time Protocol (SNTP) enables you to adjust the system clock by using the time server on the network. When you use SNTP, the system checks the time server periodically, so that the system clock is always accurate.

The SNTP of the machine supports both NTP (version 3) and SNTP (versions 3 and 4) servers.
