Time & Frequency Services

The National Institute of Standards and Technology is responsible for maintaining and disseminating official time in the United States. While NIST does not have a direct role in implementing clock changes for daylight saving time, it does play an important role in ensuring that timekeeping systems across the country are accurate and consistent.

Prior to the implementation of daylight saving time, NIST issues public announcements reminding individuals and organizations to adjust their clocks accordingly. NIST also provides resources to help people synchronize their clocks, such as the time.gov website and the NIST radio station WWV.

In addition, NIST is responsible for developing and maintaining the atomic clocks that are used to define Coordinated Universal Time (UTC), the international standard for timekeeping. UTC is used as the basis for all civil time in the United States, and it is the reference time used by many systems, including the Global Positioning System (GPS) and the internet.

Overall, while NIST does not have a direct role in implementing clock changes for daylight saving time, it plays an important role in ensuring that timekeeping systems across the country are accurate and consistent, which is essential for the smooth implementation of any changes to the system.

Hosanna to the Son of David

Matthew 21:1-11 recounts the events of Palm Sunday, the triumphal entry of Jesus into Jerusalem:

1 As they approached Jerusalem and came to Bethphage on the Mount of Olives, Jesus sent two disciples, 2 saying to them, “Go to the village ahead of you, and at once you will find a donkey tied there, with her colt by her. Untie them and bring them to me. 3 If anyone says anything to you, say that the Lord needs them, and he will send them right away.”

4 This took place to fulfill what was spoken through the prophet: 5 “Say to Daughter Zion, ‘See, your king comes to you, gentle and riding on a donkey, and on a colt, the foal of a donkey.'”

6 The disciples went and did as Jesus had instructed them. 7 They brought the donkey and the colt and placed their cloaks on them for Jesus to sit on. 8 A very large crowd spread their cloaks on the road, while others cut branches from the trees and spread them on the road. 9 The crowds that went ahead of him and those that followed shouted, “Hosanna to the Son of David!” “Blessed is he who comes in the name of the Lord!” “Hosanna in the highest heaven!”

10 When Jesus entered Jerusalem, the whole city was stirred and asked, “Who is this?”

11 The crowds answered, “This is Jesus, the prophet from Nazareth in Galilee.”

The term “Hosanna” originates from Hebrew and is often translated as “Save, we pray” or “Save us, we pray.” It is an expression of adoration, praise, and supplication.  It’s origins lie in the events of Palm Sunday, which commemorates Jesus Christ’s triumphant entry into Jerusalem. According to the Gospels, Jesus rode into Jerusalem on a donkey while crowds of people laid palm branches and their cloaks on the road, shouting “Hosanna to the Son of David! Blessed is he who comes in the name of the Lord! Hosanna in the highest heaven!”

Mechanical Clock from 1895 Still Ticking

Located in the Mechanical Engineering Building this clock has been keeping time for over 120 years and its ticking can be heard throughout the building. The clock was built by the Seth Thomas Clock Company and was installed in 1904.

The clock’s mechanism is powered by weights that are wound up manually twice a week. It has a pendulum that swings back and forth, keeping time with remarkable accuracy. The clock is also equipped with a chime that rings every quarter hour, as well as a striking mechanism that sounds the hours.

Over the years, the clock has undergone several renovations and restorations to keep it in good working order. In 2009, the clock was fitted with an electric motor to assist in winding the weights, but it still operates primarily through mechanical means.

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.

“Kommt, eilet und laufet” 1725 Johann Sebastian Bach

The choir was founded in the late 15th century by King Henry VI, who established King’s College as a center of learning and worship; respected for its high standards of performance and its repertoire of traditional choral music.  

The choir is composed of 16 choristers, who are boys between the ages of 7 and 13, and 14 choral scholars, who are undergraduate students at the university. The choristers receive a full scholarship to attend King’s College School and to sing in the choir, and many of them go on to pursue successful careers in music.
