Note

If it is likely that the value used is to be compared with another, then a time zone indicator should always be included, and only the dateTime representation should be used.

For all representations for which ISO 8601 describes both a basic and an extended format, these Guidelines recommend use of the extended format.

While ISO 8601 permits the use of both 00:00 and 24:00 to represent midnight, these Guidelines strongly recommend against the use of 24:00.
