What is time?

“What then is time? If no one asks me, I know what it is.

If I wish to explain it to him who asks, I do not know.”

“Time flies like an arrow; fruit flies like a banana.” — Groucho Marx

“Time is a great healer, but a terrible beautician.” — Unknown

“Time and tide wait for no man, but time always stands still for a woman of 30.” — Robert Frost

“Time is what we want most, but what we use worst.” — William Penn

“Time is the best teacher; unfortunately, it kills all its students.” — Robin Williams

“Inside every older person is a younger person wondering what happened.” — Jennifer Yane

“Age is an issue of mind over matter. If you don’t mind, it doesn’t matter.” — Mark Twain

“They say time is a great teacher, but unfortunately it kills all its pupils.” — Louis Hector Berlioz

“Middle age is when you’re sitting at home on a Saturday night and the telephone rings, and you hope it isn’t for you.” — Ogden Nash

Date & Time: Representations For Information Interchange

“A Philosopher Lecturing on the Orrery” | Joseph Wright (1766)

Most nations follow the day/month/year format (07/01/19 for January 7, 2019, for example), but the United States adheres to its own format of month/day/year (1/7/19 or 1/7/2019). The potential for misinterpreting dates across national boundaries is the logic for ISO 8601:2019 – Data Elements And Interchange Formats – Information Interchange – Representation Of Dates And Times, the ISO format for dates represents year, month, and day from the largest unit to the smallest, most specific unit of time. The ISO date format is the date format used in SQL and is the default date setting on many computers.

Global Positioning System: A Generation of Service to the World

Citizens of the Earth depend upon United States leadership in this technology for several reasons:

Development: The GPS was originally developed by the US Department of Defense for military purposes, but it was later made available for civilian use. The US has invested heavily in the development and maintenance of the system, which has contributed to its leadership in this area.

Coverage: The GPS provides global coverage, with 24 satellites orbiting the earth and transmitting signals that can be received by GPS receivers anywhere in the world. This level of coverage is unmatched by any other global navigation system.

Accuracy: The US has worked to continually improve the accuracy of the GPS, with current accuracy levels estimated at around 10 meters for civilian users and even higher accuracy for military users.

Innovation: The US has continued to innovate and expand the capabilities of the GPS over time, with newer versions of the system including features such as higher accuracy, improved anti-jamming capabilities, and the ability to operate in more challenging environments such as indoors or in urban canyons.

Collaboration: The US has collaborated with other countries to expand the reach and capabilities of the GPS, such as through the development of compatible navigation systems like the European Union’s Galileo system and Japan’s QZSS system.

United States leadership in the GPS has been driven by a combination of investment, innovation, collaboration, and a commitment to improving the accuracy and capabilities of the system over time.

“Indianapolis hosted the Trials in 1924 when that Olympic team swam in Paris. One hundred years later, Trials are back in Indy as a team is selected for the Paris 2024 Olympic Games. The nation’s fastest swimmers will take to the water at Lucas Oil Stadium – the first time a pool will be built in an NFL Stadium.” — USA Swimming

Tyme

“Tyme” was used in Middle English and earlier forms of the language, and it was commonly found in historical texts, poetry, and manuscripts of that time. It was used to refer to the passage of time, an era, or a specific moment in history.

Today at 16:00 UTC we refresh our understanding of the technical standards for the timing-systems that maintain the temporal framework for daily life in education communities. The campus clock continues as a monument of beauty and structure even though digitization of everything has rendered the central community clock redundant.

Most leading practice discovery (and innovation) is happening with the Network Time Protocols (NTP) that synchronize the time stamps of widely separated data centers. In operation since before 1985, NTP is one of the oldest Internet protocols in current use and underlies the Internet of Things build out. NTP is particularly important in maintaining accurate time stamps for safety system coordination and for time stamps on email log messages.
