= What is the Bully Row time system? =
[https://en.m.wikiversity.org/wiki/Bully_Timestamps Bully Timestamps (Wikiversity Page)]
 
The '''Bully Row''' time system is neither a clock nor a calendar.  Clocks are tied to the rotation of the Earth and measure time 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, and from the precession of the Earth's rotational axis.  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.
 
The Bully Row time system is not tied to the rotation of the Earth, and is only marginally related to the Earth's orbit (in ways that will be explained in an upcoming Youtube video). Since clocks and calendars are tied to the motion of the Earth, and these movements are somewhat irregular, it becomes necessary from time to time to insert leap seconds, or other corrections, to keep clocks and calendars in sync with the Earth's actual orientation. The Bully Row time system is not directly tied to the motions of the Earth, and hence, it is never necessary to insert leap seconds or other corrections into Bully Row timestamps. The Bully Row time system is directly related to International Atomic Time (TAI), which is the passage of time as measured with atomic clocks.
 
=== Timespan described by Bully Row timestamps ===
 
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:
 
<math display="block">{16}^{12} \cdot 3055\ seconds = 27,249,360,000\ years</math>
 
[[History of Earth]]
 
=== Realized vs. Estimated Bully Row timestamps ===
 
Each Bully Row timestamp is realized 3055 seconds TAI after the previous one, to a required accuracy of <math>{10}^{-11}</math>. Since atomic clocks did not exist prior to the 1950's, any assignment of Bully Row timestamps prior to 1950 should be viewed as an estimate of how time transpired in the past, rather than an actual realization of Bully Row time. Also, given the current availability and accuracy of atomic clocks, it is anticipated that future Bully Row timestamps will continue to be realized with great regularity.  However, due to the uncertainty of the future and limits of human knowledge, future timestamps should be viewed as estimates of what might happen in the future.  A Bully Row timestamp should not be considered "realized" until after it occurs and is measured using precise clocks. 
 
 
Furthermore, due to leap second insertions, and other corrections that have occurred, or will occur, in clocks and calendars, it is impossible to predict the long term relationship between the issuing of Bully Row timestamps and standard wall clock time, which uses Coordinated Universal Time (UTC). To clear up uncertainty, the following table (derived from the Wikipedia "Leap Second" article), lists all leap second insertions that have occurred since the introduction of modern time keeping.  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 noting in the below table.  The TAI and UTC already differed by 10 seconds at the beginning of 1972, so when Bully Row Timestamp 8209 28E5 DFFB was realized, the TAI time was 1972-06-30 23:34:45 TAI, whereas UTC time was 1972-06-30 23:34:35 UTC. An additional 27 leap seconds have been inserted into UTC during the fifty year period between 1972 and 2022, making a total of 37 leap seconds difference, so when Bully Row Timestamp 8209 28EC E3C0 was realized, the TAI time was 2017-01-01 00:32:00 TAI, whereas UTC time was 2017-01-01 00:31:23 UTC.  You will also note that Bully Row timestamps are realized during TAI times with a seconds value ending in five or zero. The Bully Row and TAI both measure elapsed time as determined by atomic clocks, so these systems will always have this simple relationship.
