UTC offsets are the differences in hours and minutes from Coordinated Universal Time (UTC), which is the primary time standard used worldwide. Each location on Earth has a specific offset that indicates how many hours ahead or behind it is from UTC. For example, if a place has a UTC offset of +2:00, it is two hours ahead of UTC. These offsets can change due to daylight saving time, where clocks are adjusted forward or backward by one hour during certain months. This means that a location's UTC offset may vary throughout the year, affecting how time is calculated globally.
