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, NIST or similar time signals.
This package contains HTML documentation for the ntp packages (ntp, ntpdate). Since there are no substantive man pages for ntp's programs and configuration files, this package is desirable for any setup beyond the simple default configuration.
