Time Zone Information
Coordinated Universal Time (UTC)
UTC is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time at 0° longitude.
Time Zone Offsets
Time zones are expressed as offsets from UTC, ranging from UTC-12:00 to UTC+14:00. The offset indicates how many hours the time zone is ahead or behind UTC.
Daylight Saving Time (DST)
DST is the practice of advancing clocks during warmer months so that darkness falls later each day. Not all countries observe DST, and start/end dates vary.
International Date Line
The International Date Line is an imaginary line that runs from the North Pole to the South Pole. When you cross it, the date changes by one day.
