The SNTP (Simple Network Time Protocol) is a simplified version or subnet of the NTP protocol. It is used to synchronize the time and date by contacting the SNTP Server. The administrator can choose whether to set the system clock manually or to enable SNTP. If SNTP is enabled, the SNTP implementation discovers the SNTP server and gets the time from the server. The SNTP implementation also has callouts to set the system time based on the time received from the SNTP server. It supports different time zones, where the user can set the required time zone.
