Coordinated Universal Time
Coordinated Universal Time (UTC) is the common
time standard across the world.
This 24-hour time standard is kept using highly precise
atomic clocks combined with the Earth's rotation.
Greenwich Mean Time (GMT) is often interchanged
or confused with UTC, but GMT is a time zone and
UTC is a time standard.
