Clock management on Linux

[ Thanks to linuxaria for this link. ]

"The Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks.

"NTP provides Coordinated Universal Time (UTC). No information about time zones or daylight saving time is transmitted; this information is outside its scope and must be obtained separately. In isolated LANs, NTP could in principle be used to distribute a different time scale (e.g. local zone time), but this is uncommon NTPDATE

"ntpdate is a computer program used to synchronize and set computers' date and time by polling the Network Time Protocol (NTP) server(s)."
