UTC (Coordinated Universal Time) is the official global time standard, based on precise atomic clocks. It serves as the reference for time zones worldwide; for instance, Korea operates on UTC+9, meaning it is 9 hours ahead of UTC. In contrast, UNIX Time represents a different method for recording timestamps, counting seconds from midnight UTC on January 1, 1970, and ignores leap seconds that arise from Earth's rotational discrepancies. Leap seconds occasionally alter the standard day length of 86,400 seconds to maintain accuracy in timekeeping.
UTC, or Coordinated Universal Time, is the official time standard used globally, determined by atomic clocks, ensuring accuracy and consistency in timekeeping.
Korean time is expressed as UTC+9, meaning it is 9 hours ahead of UTC. In contrast, UK time is UTC+0, and Greenland is UTC-2.
UNIX Time is a method of timestamping that counts the seconds from January 1, 1970, 00:00:00 UTC, ignoring leap seconds, which adds to timekeeping precision.
Leap seconds, added to account for irregularities in Earth's rotation, can cause days to have either 86,400 or 86,401 seconds, crucial for accurate timekeeping.
