Daylight Saving Time

The time shift results in sunrise and sunset occurring approximately one hour later on the clock than the day before, providing more daylight in the evening and less in the morning.

Start Date
: Daylight Saving Time begins on Sunday, March 9, 2025. This is the second Sunday in March, following the schedule established by theEnergy Policy Act of 2005.
Time Change: At 2:00 a.m. local standard time, clocks are set forward one hour to 3:00 a.m. local daylight time. This is often referred to as “springing forward.”
Geographic ScopeMost of the United States observes DST, except for Hawaii and most of Arizona (with the exception of the Navajo Nation, which does observe DST).  U.S. territories such as American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands do not participate in DST.
Legal Basis: The rules are governed by the Uniform Time Act of 1966, as amended by the Energy Policy Act of 2005. The U.S. Department of Transportation oversees the implementation, while states and territories have the option to opt out of DST but cannot independently choose to make it permanent without federal approval.

The U.S. power grid operates on a synchronized frequency of 60 Hz, maintained across three major interconnections: Eastern, Western, and Texas. During the Daylight Saving Time (DST) switch—typically at 2:00 AM local time on the second Sunday in March (spring forward) or the first Sunday in November (fall back)—the grid’s synchronization is unaffected because it relies on Coordinated Universal Time (UTC), not local time. Grid operators, coordinated by entities like the North American Electric Reliability Corporation (NERC), ensure frequency stability through automatic generation control (AGC) systems, which adjust power output to match demand in real time.

Ω

The DST shift doesn’t disrupt this process. When clocks spring forward (e.g., 2:00 AM becomes 3:00 AM), demand may briefly drop as human activity adjusts, but AGC systems respond instantly, balancing generation and load. In the fall, when clocks fall back (e.g., 2:00 AM repeats), a temporary demand spike might occur, but the grid’s inertial stability—provided by large rotating generators—and real-time monitoring prevent desynchronization. Operators may pre-schedule minor adjustments, but the system’s design, rooted in UTC-based frequency regulation, ensures seamless operation. Thus, while local time shifts, the grid’s 60 Hz hum remains steady across the transition.

Number of servings per recipe: 8

Ingredients:

  • 1/4 cup flour
  • 2 cups turkey stock
  • 4 cups fat free milk
  • 2 large celery stalks, chopped
  • 1 1/2 cups chopped onion
  • 8 oz sliced cremini mushrooms
  • Salt and pepper to taste
  • 2 Tablespoons chopped parsley
  • 8 oz frozen peas and carrots
  • 1 teaspoon turkey bullion
  • 2 medium potatoes, cubed small
  • 16 oz cooked turkey breast, diced small or shredded

Directions:

  • 1.Create a slurry by combining 1/2 cup of the cold broth with flour in a medium bowl and whisk until well blended. Set aside.
  • 2.Pour remaining broth and milk into a large pot and slowly bring to a boil.
  • 3.Add celery, onion, mushrooms, parsley, fresh pepper, frozen vegetables, and bullion, and return to a boil. Partially cover and simmer on low until vegetables are soft, about 20 minutes.
  • 4.Remove lid, add potatoes and cook until soft, about 5 minutes.
  • 5.Add turkey, and slowly whisk in slurry, stirring well as you add. Cook another 2-3 minutes, until soup thickens, adjust salt and pepper to taste and serve.

Heat tracing is a process used to maintain or raise the temperature of pipes and vessels in order to prevent freezing, maintain process temperature, or ensure that products remain fluid and flow through the system properly.  Without electric heat tracing; much of the earth would be uninhabitable.

Heat tracing works by using an electric heating cable or tape that is wrapped around the pipe or vessel, and then insulated to help retain the heat. The heating cable is connected to a power source and temperature control system that maintains the desired temperature by regulating the amount of heat output from the cable. Heat tracing is commonly used in industrial applications where temperature control is critical, such as in chemical plants, refineries, and oil and gas facilities.

There are several types of heat tracing, including electric heat tracing, steam tracing, and hot water tracing, each of which have their own unique advantages and disadvantages. The selection of the appropriate type of heat tracing depends on the specific application and the required temperature range, as well as factors such as cost, maintenance, and safety considerations.

There have been several recent innovations that have made it possible for construction activity to continue through cold winter months. Some of the most notable ones include:

  1. Heated Job Site Trailers: These trailers are equipped with heating systems that keep workers warm and comfortable while they take breaks or work on plans. This helps to keep morale up and prevent cold-related health issues.
  2. Insulated Concrete Forms (ICFs): ICFs are prefabricated blocks made of foam insulation that are stacked together to form the walls of a building. The foam insulation provides an extra layer of insulation to keep the building warm during cold winter months.
  3. Warm-Mix Asphalt (WMA): WMA is a type of asphalt that is designed to be used in colder temperatures than traditional hot-mix asphalt. This allows road construction crews to work through the winter months without having to worry about the asphalt cooling and becoming unusable.
  4. Pneumatic Heaters: These heaters are used to warm up the ground before concrete is poured. This helps to prevent the concrete from freezing and becoming damaged during the winter months.
  5. Electrically Heated Mats: These mats are placed on the ground to prevent snow and ice from accumulating. This helps to make the job site safer and easier to work on during the winter months.

Overall, these innovations have made it possible for construction crews to work through the winter months more comfortably and safely, which has helped to keep projects on schedule and minimize delays.

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.
