What Is UTC (Coordinated Universal Time)?
UTC is the global time standard from which all time zones are defined as offsets, like UTC+5 or UTC−8.
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks. Every time zone is expressed as an offset from it: New York is UTC−5 (winter), Pakistan UTC+5, Japan UTC+9. UTC itself never observes daylight saving time.
Servers, logs, aviation and international systems run on UTC precisely because it is unambiguous — an event stamped 14:00 UTC is the same instant everywhere. Local display times are derived from it at the last moment.
