NTP network time protocol (RFC 1119, RFC 1305)
used to synchronize the time and clock on your computers (servers and
clients) with each other.
Through assumption made ond roud trip times and latency being equal for
packets sent and received from/to the same site and some averaging of the
returned values with adjustments for time difference cause by latency, it
is possible for a client to get a message from a server on the present
time and have it still be rather accurate for most intensive purposes of
home users and many larger networks. Real-time sampling systems that need
more accurate timing systems may choose other systems, but this works for
most avergae file time-stamping.
More descriptions can be found in the RFCs mentioned above and in man
pages associated with the packes that include *ntp.
