Network Time Protocol
This results in an extra hour of daylight in the evening during the summer months, but it means that the sun rises and sets an hour earlier in the morning and evening, respectively, in the winter months. Real Time Clock ( RTC ) – Your computer keeps time even when it's turned off using a chip called an RTC. When it's not charging, a tiny lithium battery keeps the chip stable (pun intended) and can run it for up to ten years without a charge.Network Time Protocol ( NTP ) – When operating systems have an established America Cell Phone Number List connection to the Internet, they use NTP to synchronize their clocks with a pool of time servers. Network Time Protocol . By default, Windows synchronizes with NTP servers once every days, while macOS synchronizes once every hour. NTP uses Coordinated Universal Time ( UTC ). When a client queries an NTP server for the current time.

The server responds with a -bit value representing the number of seconds since January , at :: UTC. Coordinated Universal Time ( UTC ) is a standardized time used as the basis for all timekeeping in the world. It is based on International Atomic Time (TAI), which measures the mean time between two known points in the Earth's Moon's orbit. UTC was first implemented in as a successor to TAI and Greenwich Mean Time ( GMT ). UTC is kept to within seconds of the TAI time scale, and its accuracy is maintained using atomic clocks and other timing technologies.
