How Does UTC Offset Work?
UTC offset is used to express the local time at any location on Earth relative to UTC. The offset is generally represented in hours and minutes, either ahead or behind UTC.
Working of UTC Offset:
- Earth divided is into 24 time zones, each corresponding to 15 degrees of longitude. Each time zone represents a one-hour difference from adjacent zones.
- UTC offsets for specific locations are calculated by determining the difference of several hours and minutes between UTC and the local time.
- Positive offset indicates locations ahead of UTC, while negative offset indicates locations behind UTC.
UTC offsets are subject to changes due to political uproars, changes in time zone boundaries or adjustments in response to scientific discoveries.
Daylight Saving Time is one important aspect of UTC. Some regions in the world observe DST, where clocks are adjusted forward by one hour during certain months of the year to make better use of the daylight. When DST is in effect, UTC changes for the time.
