Time Zone Information
Time zones are regions of the globe that observe a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time.
UTC (Universal Time Coordinated)
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 and is not adjusted for daylight saving time.
Daylight Saving Time (DST)
The practice of advancing clocks during warmer months so that darkness falls later each day according to the clock. Typically, regions that use daylight saving time adjust clocks forward one hour close to the start of spring and adjust them backward in the autumn.
Time Zone Offset
The difference in hours and minutes from Coordinated Universal Time (UTC). For example, Eastern Standard Time (EST) has an offset of UTC-5, meaning it is 5 hours behind UTC.
