Slave clock synchronization is usually achieved by phase-locking the slave clock signal to a signal received from the master clock. To adjust for the transit time of the signal from the master clock to the slave clock, the phase of the slave clocks are adjusted so that both clocks are in phase.
A modern LF radio-controlled clock. A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly [1]) referred to as an "atomic clock", is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.
The telegraphic distribution of time signals was made obsolete by the use of AM, FM, shortwave radio, Internet Network Time Protocol servers as well as atomic clocks in satellite navigation systems. Time signals have been transmitted by radio since 1905. [12] There are dedicated radio time signal stations around the world.

Best: Higher accuracy is possible with a high-end GPS receiver designed for time signal use, but these are very expensive (around $1000), feature OCXOs (oven-controlled crystal oscillators), and often require special software and physical RS-232 ports not connected via a USB bus to achieve that accuracy.

In the United States "special needs" is a legal term applying in foster care, derived from the language in the Adoption and Safe Families Act of 1997. It is a diagnosis used to classify children as needing more services than those children without special needs who are in the foster care system.
An Individualized Education Program (IEP) is a legal document under United States law that is developed for each public school child in the U.S. who needs special education. [1] IEPs must be reviewed every year to keep track of the child's educational progress. [2] Similar legal documents exist in other countries. [3]
