Leap Seconds and Why They Matter

Subject: Static GK (General Knowledge)

Book: General Time Knowledge

Leap seconds are occasional one-second adjustments added to Coordinated Universal Time to account for irregularities in Earth’s rotation. Although a single second might seem trivial, precise timing is critical for GPS, telecommunications, and scientific measurements. Debates arise over whether to abolish leap seconds due to the cost and complexity of updating global systems. Many seek information on leap seconds after hearing about them in the news or encountering odd timestamps in computer logs. Ultimately, these tiny increments preserve the delicate alignment between atomic time and astronomical reality.
