ntpsec - 1.2.2+dfsg1-1+deb12u1 main

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.
.
This package contains the NTP daemon and utility programs. An NTP
daemon needs to be running on each host that is to have its clock
accuracy controlled by NTP. The same NTP daemon is also used to
provide NTP service to other hosts.
.
This is the NTPsec version of NTP. NTPsec is a secure, hardened,
and improved implementation derived from the original NTP project.
NTPsec supports Network Time Security (NTS) which provides
cryptographically authenticated time.
.

configuration and operation, install the package "ntpsec-doc".
