Quartz Compositor is the display server (and at the same time the compositing window manager) in macOS. It is responsible for presenting and maintaining rasterized , rendered graphics from the rest of the Core Graphics framework and other renderers in the Quartz technologies family.
The utility can schedule wake, sleep, power on or power off events. Events can be recurring based on arbitrary weekday and time combinations, or scheduled for future dates and times. The syntax for scheduling an event is as follows: pmset [repeat, schedule] [sleep, wake, poweron, shutdown, wakeorpoweron] [<MTWRFSU> <date/time>]
XQuartz is an open-source version of the X.Org X server, a display server for the X Window System (sometimes shortened to X11 or X) that runs on macOS. [1] In 2012, it formally replaced Apple's internal X11 app for OS X Mountain Lion (version 10.8).
The Precision Time Protocol (PTP) is a protocol for clock synchronization throughout a computer network with relatively high precision and therefore potentially high accuracy. In a local area network (LAN), accuracy can be sub-microsecond – making it suitable for measurement and control systems. [ 1 ]
In contrast to standard Ethernet according to IEEE 802.3 and Ethernet bridging according to IEEE 802.1Q, time is very important in TSN networks.For real-time communication with hard, non-negotiable time boundaries for end-to-end transmission latencies, all devices in this network need to have a common time reference and therefore, need to synchronize their clocks among each other.
The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use. NTP was designed by David L. Mills of the University of Delaware.
