UTC Offset: UTC+0 / UTC+1
A UTC offset tells you how many hours (and sometimes half-hours) a location is ahead of or behind Coordinated Universal Time. London's offset of UTC+0 means that when it is 12:00 noon UTC, it is 12:00 (12:00 PM) in London.
During Daylight Saving Time, this offset temporarily changes to UTC+1, effectively moving the clock one hour forward to extend usable evening daylight. This adjustment can affect scheduling with international partners, so it is important to check the current offset before arranging calls or meetings.
