ntpdig SNTP client

NTP, the Network Time Protocol, is used to keep computer clocks accurate by synchronizing them over the Internet or a local network, or by following an accurate hardware receiver that interprets GPS, DCF-77, or similar time signals.

ntpdig can be used as an SNTP client to query a NTP or SNTP server and either display the time or set the local system's time. It is not sufficient, however, for maintaining an accurate clock in the long run.

This is the NTPsec version of ntpdig, which is equivalent to the sntp utility. NTPsec is a secure, hardened, and improved implementation derived from the original NTP project.
