Network Time Protocol documentation
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 HTML documentation for the ntpsec packages (ntpsec, ntpsec-ntpdate).
This is part of NTPsec. NTPsec is a secure, hardened, and improved implementation derived from the original NTP project.
