ntpsec-ntpviz

NTP statistics graphing utility

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. ntpviz analyzes NTP log files and generates statistical plots from them. The output is in the form of HTML with images. If Apache is installed, it will be served at: /ntpviz This is part of NTPsec. NTPsec is a secure, hardened, and improved implementation derived from the original NTP project.
