Network Time Protocol: daemon for simple systems
 NTP, the Network Time Protocol, is used to keep computer clocks accurate
 over the Internet, or by following an accurate hardware receiver which
 interprets GPS, DCF-77, NIST or similar time signals.
 .
 This version of the ntp daemon can synchronize to other servers across
 the Internet, or (if none are available) use your computer's built-in
 clock as a time source for a local network. It is sufficient for most
 systems.
 .
 If you wish to configure a reference clock, particularly if you have a radio
 clock, use the ntp-refclock package instead.
