Configuring the Date and Time

when it connects to the Internet. Alternatively, the date and time can be configured manually.
NTP is a protocol for distributing the Coordinated Universal Time (UTC) by means of
synchronizing the clocks of computer systems over packet-switched, variable-latency data
networks.
