It's the world spinning around the Sun or shift workers hopping between night and day, our time is affected by a myriad of events. Certain of these events occur every day, while others are less predictable and more irregular.

For instance, the majority of people are aware that the Earth revolves around the Sun every day. The thing that is less well-known is the speed at which the Earth revolves can be different, making the day appear to be shorter or longer than what is expected. The atomic clocks, which maintain an established time, have to be adjusted regularly by adding or subtracting seconds. This change is called a leap second.

Precession is a common rotating event. It is the oscillation of the Earth's axis similar to the spinning top of a toy that is a little off-center. This axial shift in relation to fixed stars (inertial spaces) has the duration of 25,771.5. It is the cause for many weather patterns, for example, the alternating direction between cyclones in the Northern and Southern Hemispheres.

Scientists have also observed that the speed of Earth rotation slows over time, leading solar day to get longer. That's why on June 29, the world added one second leap to atomic clocks in order that they could better match up with the actual Earth's rotation. Although the addition of a single second may seem minor, it has important implications for businesses that depend on changing schedules and rotating times. For example, for multinational companies that rely on employees from all over the world, fumbling through static spreadsheets and wiki pages to manage changing call schedules could be costly in terms of revenue and reputation. On-call rotation software is becoming well-known as it helps reduce interruptions to service and manages the coverage of transfers and gives employees a clearer picture of the situation.
