ntpsec-ntpdate - 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.
.
ntpdate is a simple NTP client that sets a system's clock to match
the time obtained by communicating with one or more NTP servers. It
is not sufficient, however, for maintaining an accurate clock in the
long run. ntpdate by itself is useful for occasionally setting the
time on machines that do not have full-time network access, such as
laptops.
.
This is the NTPsec version of ntpdate. NTPsec is a secure, hardened,
and improved implementation derived from the original NTP project.
.
If the full NTP daemon from the package "ntpsec" is installed, then
ntpsec-ntpdate is not necessary.
