When did UTC become a standard?
Coordinated Universal Time or UTC is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce.

Coordinated Universal Time (or UTC) is the standard time system of the world. It is the standard by which the world regulates clocks and time. It is, within about 1 second, mean solar time at 0° longitude. The standard before was Greenwich Mean Time (GMT). UTC and GMT are almost the same.
If a time is in Coordinated Universal Time (UTC), a "Z" is added directly after the time without a separating space. "Z" is the zone designator for the zero UTC offset. "09:30 UTC" is therefore represented as "09:30Z" or "0930Z". Likewise, "14:45:15 UTC" is written as "14:45:15Z" or "144515Z". [27]
The UTC offset (or time offset) is an amount of time subtracted from or added to Coordinated Universal Time (UTC) time to specify the local solar time (which may not be the current civil time, whether it is standard time or daylight saving time).
