Time element modeling and management
Generally, representations of the date cover the year, month, and day elements. Some of them can be omitted, or a transformation can be made to express the relevant value. This standard proposes a definition for time elements as well. The principles and model properties are similar. It uses a 24-hour clock by pointing to the hour (HH), minute (MI), and second (SS) elements. The time value is prefixed with T. The basic format does not use padding; for example, T152217. Instead, each element is composed of 2 digits. The extended format is more user-friendly, splitting individual parts into categories – for example, T15:22:17. In both models, the character T expresses the time representation but can be omitted for extended representation by applying a colon delimiter.
The hour value ranges from 00 to 24. The minute value ranges from 00 to 59, and finally, for seconds, the available range is from 00 to 60 (due to the leap second discussed...
