UTC (Universal Time Coordinated)

UTC, also known as Universal Coordinated Time or Coordinated Universal Time, replaced Greenwich Mean Time (GMT) as the time calculation by which all time zones calculate their times in 1961. It’s based on International Atomic Time (TAI), a high-precision time calculation which is arrived at by taking an average time from more than 200 atomic clocks located around the world, although UTC is slightly behind International Atomic Time.

The word’s time zones are usually shown as either as a positive offset from UTC (i.e. ‘+’ a specified number of hours UTC, meaning ahead of UTC) or a negative offset (i.e. ‘-’ a specified number of hours UTC, meaning behind UTC).
