UTC Time FAQ
What is UTC time?
UTC, or Coordinated Universal Time, is the global reference time used by systems, aviation, software, logs, and international coordination.
Is UTC the same as GMT?
GMT is a historical reference timezone, while UTC is the modern time standard. They often show the same clock time.
Why should logs use UTC?
