Understanding Time Formats
What is Unix Time?
Unix time (or Epoch time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It is widely used in computing because it represents time as a single number, making it easy to sort and calculate differences.
What is ISO 8601?
ISO 8601 is the international standard for representing dates and times. It typically looks like `YYYY-MM-DDTHH:mm:ss.sssZ`. The `Z` at the end indicates UTC time (Zulu time), ensuring no ambiguity across time zones.
