This is the time of the year when power over ethernet clocks, often referred to as PoE clocks, get a lot of attention. Classrooms full of students counting down the last minutes of the day during the last weeks of the school year. Outside of the classroom, of course, there are many other times when different kinds of clocks serve very different kinds of purposes. From the WiFi digital clocks in many public spaces to the digital scorekeeper on a soccer field or on a track, time is an important commodity that many people spend a good deal of time tracking and recording.
PoE clocks deliver both power and time updates through one cable connected to the Ethernet. As a result, an entire building can have the same time displayed in every room. This is especially important in a school setting where a bell schedule has to be exact so that students know when they should come to class and when it is time to go. There are many workplaces as well where Poe network clocks are necessary. From large companies that offer overtime to smaller factories that need to be ready for deliveries and scheduled breaks, there are many situations where keeping track of time is essential. Even in hospital settings where nurses are required to chart specific times for medications and treatments, it is important to have standardized time keeping devices where everyone can see them.

Time Is an Important Part of the History of the World
The ancient Egyptians were the first to tell time by using obelisks as primitive sundials, while the first mechanical clocks were invented in Europe in the 14th century. These efforts were the start of the process of humans keeping time for the last 5,000 to 6,000 years. In operation since before the year 1985, Network Time Protocol (NTP) is one of the oldest Internet protocols still in use today, and nearly all Americans rely on accurate time for their jobs, their travel schedules, and nearly every aspect of their life.
Whether you are a student in a classroom counting down the last few minutes of the day of one of he last weeks of the year or you are someone who needs to clock in and out of a factory job, time keeping is an essential part of the lives that we live.
