Realized Bully Time There have been over 655360 realized Bully Row timestamps (8209 28E4 0000 ... 8209 28EE 0000) during the 66 years of modern atomic time keeping (1958 AD ... 2024 AD). Given the availability of atomic clocks, it is anticipated that Bully Row timestamps will continue to be realized with great regularity for the foreseeable future. Each Bully Row timestamp should be considered "realized" after it occurs and is measured using precise clocks. To avoid uncertainty, the following table (derived from the Wikipedia "Leap Second" article), lists all leap second insertions that have occurred since the introduction of leap seconds. For each leap second insertion, the below table lists the preceding Bully Row timestamp (that had been "realized" immediately prior to the leap second insertion), and the subsequent Bully Row timestamp (that was "realized" immediately after the leap second insertion). A few details are worth no...

History of Earth The history of Earth is divided into four great eons, starting 4,540 million years ago with the formation of the planet. The following table lists estimated Bully Row timestamps for each eon, and also describes significant changes in Earth's composition, climate, and life. The Archean and subsequent eons are divided into eras (click "Bully Row timeline" links below), which in turn are divided into periods and further divided into epochs. The text for this table was copied from Wikipedia to provide context for the listed Bully Row timestamps. Estimated Bully Row Timestamp Eon Description 5720 9200 0000 Hadean Eon The Earth is formed out of debris around the solar protoplanetary disk . There is no life. Temperatures are extremely hot, with frequent volcanic activity and hellish-looking environments (hence the eon's name, which comes from Hades ). The atmosphere is nebular. Possible early oceans or bodies of liquid water. The...
Realized vs. Estimated Bully Row timestamps Each Bully Row timestamp is realized exactly 3055 seconds TAI after the previous one. However, since atomic time standards did not exist prior to the 1950's, any assignment of Bully Row timestamps prior to 1958 should be viewed as an estimate of how elapsed time might have transpired in the past, rather than an actual realization of Bully Row time. Bully Row time should only be considered "realized" when time is measured with an accuracy of 10 − 10 .
The second is broken The following table includes quotes and links to articles from contexts where the current definition of the second is broken. This issue is causing confusion and unnecessary expense, as individuals and corporations are forced to navigate through this broken system. JULY 25, 2022 It’s time to leave the leap second in the past "While the leap second might have been an acceptable solution in 1972, when it made both the scientific community and the telecom industry happy, these days UTC is equally bad for both digital applications and scientists, who often choose TAI or UT1 instead." "At Meta, we’re supporting an industry effort to stop future introductions of leap seconds and . . . we believe it is time to introduce new technologies to replace it." "At best, such a time jump crashed programs or even corrupted data, due to weird timestamps in the data storage." "The impact of a negative leap second has never been tes...
Why do we need Bully Row timestamps It is impossible to predict the exact long term relationship that will exist between elapsed time and wall clock time (which is based on the Earth's orientation). Leap second insertions, along with other clock and calendar corrections, were designed to accommodate for uncertainties in Earth's motion, but since these variations are unpredictable, they can not be pre-programmed into computer hardware or software. The inability of computers to account for unpredictable variations in Earth's motion has resulted in the creation of multiple time standards. Each standard is a reflection of circumstances that existed during the deployment of a particular system. For example, as shown in figure 1 above, The GPS system was deployed January 6, 1980. At that time, there was a Delta T adjustment (TT-UTC) of more than 51 "leap" seconds. The LORAN-C upgrade, on the other hand, occurred in 1972 when the Delta T adjustment (TT-UT...
Timespan described by Bully Row timestamps 16 12 ⋅ 3055 s e c o n d s = 27 , 249 , 360 , 000 y e a r s A unique hexadecimal twelve digit Bully Row timestamp is realized every 3055 seconds TAI. The universe is currently understood to be less than 13.8 billion years old, which means that there are enough unique Bully Row timestamps to span the entire age of the universe.
What is the Bully Row time system? Figure 1 The Bully Row time system is neither a clock nor a calendar. Clocks are tied to the rotation of the Earth and measure Universal Time (UT) in terms of days and fractions of days (for example: hours , minutes , and seconds ). Calendars are tied to changes in the seasons, which result from the orbit of the Earth around the Sun ( Ephemeris time ), and from the precession of the equinoxes. Calendars measure time in terms of days, weeks, months, and years. Clocks and calendars are used for tracking biological processes such as setting a time to wake up in the morning or determining when to plant crops. It is essential for clocks and calendars to remain correlated with the earth's actual orientation for proper management of life's biological processes. Since clocks and calendars are tied to the motion of the Earth, and these motions are somewhat irregular, it becomes necessary from time to time to insert leap seconds, or mak...
