The lessons of timekeeping are part of [[engineering]] [[technology]]. In electrical engineering terms, for [[digital]] [[logic]] and data transfer, a synchronous object requires a clock signal. Timekeeping technologies such as the GPS satellites and Network time protocol (NTP) provide [[real-time]] access to a close approximation to the UTC timescale, and are used for many [[terrestrial]] synchronisation applications. | The lessons of timekeeping are part of [[engineering]] [[technology]].
