UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks and time. It is a highly precise time system that is based on atomic clocks and adjusted with leap seconds to stay in sync with the Earth's rotation. UTC serves as the universal time reference, with all time zones around the world expressed as offsets from UTC (e.g., UTC+1, UTC-5). Unlike local time zones, UTC does not observe Daylight Saving Time and remains constant throughout the year.

UTC time conversion works by adding or subtracting a specific time offset based on the local time zone relative to UTC. Each time zone around the world is expressed as an offset from UTC, either ahead (+) or behind (-) UTC.

Every location in the world has a time zone defined by an offset from UTC. For example:
      - New York (EST): UTC-5 (during standard time).
      - London: UTC+0 (same as UTC in winter).
      - Tokyo: UTC+9.

If a place is ahead of UTC (e.g., UTC+5), add the offset to the current UTC time.

If a place is behind UTC (e.g., UTC-7), subtract the offset from the current UTC time.

During DST (Daylight Saving Time), the time zone may shift by +1 hour. For example:
      - New York switches from UTC-5 to UTC-4 during summer (Eastern Daylight Time, EDT).
      - London switches from UTC+0 to UTC+1 during summer (British Summer Time, BST).

Online converters or world clocks make it easier to convert UTC to local time automatically by detecting time zones and DST changes.

UTC conversion involves adjusting the time based on your location’s time zone offset from UTC. Simply add or subtract the number of hours from the current UTC time to get the local time. More Detail
