## Key Definitions

**UTC (Coordinated Universal Time):** The primary global time standard based on atomic clocks, serving as the reference point for all time zones worldwide. Accurate to within 1 second in 300 million years.

**Time Zone:** A region that observes a uniform standard time for legal, commercial, and social purposes. Each time zone is defined by its offset from UTC (e.g., EST = UTC-5).

**Atomic Clock:** The most precise timekeeping devices, based on the vibrations of cesium-133 atoms. The SI second is defined as 9,192,631,770 periods of radiation corresponding to the transition between two energy levels of the cesium-133 atom.

**Leap Second:** An adjustment made to Coordinated Universal Time (UTC) to preserve the alignment within 0.9 seconds of UT1, which is based on the Earth's rotation. Since 1972, 27 leap seconds have been added.

## FAQ Highlights

**Q: What is the difference between UTC and GMT?**
A: Practically identical for time display (UTC±00:00 = GMT±00:00). GMT is based on astronomical observations of solar time at Greenwich, while UTC is based on atomic clocks with leap second adjustments.

**Q: How accurate is the live clock?**
A: The clock synchronizes with atomic time standards and updates in real-time with second-by-second accuracy.

**Q: Why do we need leap seconds?**
A: Earth's rotation is gradually slowing due to tidal friction from the Moon. Atomic time is perfectly consistent, but Earth time varies. Leap seconds keep them aligned within 0.9 seconds.
