Time zone abbreviations are standardized short codes (typically 2-5 letters) that represent specific geographic time zones. Examples include EST (Eastern Standard Time), GMT (Greenwich Mean Time), and JST (Japan Standard Time). These codes simplify global time communication.
UTC (Coordinated Universal Time) serves as the global time standard. All time zones are expressed as offsets from UTC, ranging from UTC-12:00 to UTC+14:00. Positive offsets are east of the Prime Meridian, while negative offsets are west.
