ntpsec-ntpdig binary package in Ubuntu Mantic ppc64el

 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.
