Our time is shaped many ways by the spin of events such as the Earth’s rotation around the Sun or shift workers switching between the night and day. Some of these occur every day but others are more irregular and unpredictable.
Most people are aware that the Earth revolves around 24 hours around the Sun. However, what is not as well-known is the speed at which the Earth rotates may vary and make a day appear shorter or longer than you would expect. The Atomic clocks, which keep an uniform time, need to be adjusted periodically by adding or subtracting a second. This is known as a leap second.
One of the most regular rotational events is precession which is the cyclical wobble of Earth’s axis for rotation, much like a spinny slightly off-center spinny toy top. This axial shift relative to fixed stars (inertial space) is a time period of 25,771.5 years, and it is responsible for various weather patterns, such as the alternating direction of cyclones in the Northern and Southern hemispheres.
Scientists have also noticed that the speed of Earth is slowing over time, causing the solar day to become longer. That’s why on June 29 the world added one second leap to atomic clocks so that they could better align with the actual rotation of our planet. While one second may seem minor, it has significant implications for businesses who rely on changing schedules. For multinational companies with a global staff managing shifty call schedules by fumbling around spreadsheets or static wiki pages can be costly in terms of revenue and reputation. This is why more organizations are switching to on-call software to cut down on service interruptions and ensure that transfer coverage is covered and offer transparency to employees.
