About ISO 8601
What is ISO 8601?
ISO 8601 is an international standard covering the worldwide exchange and communication of date and time-related data. It is maintained by the ISO.
The 'T' and 'Z'
The 'T' is just a literal to separate the date from the time. The 'Z' stands for 'Zero timezone' (UTC). Other timezones are indicated by an offset from UTC, like +08:00.
Basic vs Extended Format
Basic format minimizes the number of characters (e.g., 20240514T103000Z). Extended format incorporates separators to enhance human readability (e.g., 2024-05-14T10:30:00Z).
