The Unix epoch in ISO 8601 format is 1970-01-01T00:00:00Z.
This represents the moment when Unix time begins: midnight Coordinated Universal Time (UTC) on January 1, 1970. The "Z" at the end signifies that the time is in UTC, also sometimes referred to as Zulu time.
Here's a breakdown of the ISO 8601 format as it applies to the Unix epoch:
- YYYY: Represents the year (1970).
- MM: Represents the month (01 for January).
- DD: Represents the day (01 for the first day of the month).
- T: Separates the date and time components.
- HH: Represents the hour (00 for midnight).
- MM: Represents the minute (00).
- SS: Represents the second (00).
- Z: Indicates that the time is in UTC.
The Unix epoch is a fundamental concept in computing, serving as a reference point for tracking time in many operating systems and programming languages. Representing it in ISO 8601 format provides a standardized and unambiguous way to express this point in time.
