Detailed Description and Value Ranges
Time uses the W3C "built-in data type" xsd:time. This is structured according to the extended reavailableation of ISO 8601 (see NOTE-datetime). The reavailableation for Time is the left truncated lexical reavailableation for DateTime without optional following time zone indicator.
The extended reavailableation is as follows:
hh:mm:ss(.sss)
Example:
15:30:00
The extended representation uses the following literals:
| Code | Description | Value Range |
|---|---|---|
| hh | for hours | 00 - 23 |
| mm | for minutes | 00 - 59 |
| ss | for seconds | 00 - 59 |
| .sss | One or more characters after the decimal point represent fractions of a second. The representation is limited to a maximum of three decimal places, that is, the time can be expressed to a thousandth of a second. | |
| : | A colon between the hours, minutes, and seconds is mandatory. |
The following value ranges are defined for Time:
- Time - Represents exactly 24 hours (0 - 23)
- Minutes - Represents exactly 60 minutes (0 -59)
- Seconds - Represents exactly 60 seconds (0 -59)

Facets of Content Component
| Facet | Description | Example |
|---|---|---|
| pattern | Pattern is a constraint of the content component. The representation of pattern must be based on regular expression defined by W3C XML Schema (Part II). | [0-3][0-9]:[0-9]0:00 |
| whiteSpace | whiteSpace is a constraint of special characters in the content component. whiteSpace must be one of the following values: - preserve - No normalization (changings) of the content component - replace - All occurrences of tab (#x9), line feed (#xA), and carriage return (#xD) are replaced with space (#x20) - collapse - It implies replace. Additionally, contiguous sequences of spaces (#x20#x20....) are collapsed, and leading and trailing spaces (#x20) are truncated. |
whitSpace value="preserve|replace|collapse" |
| maxInclusive | Max Inclusive is the inclusive upper bound of the content component, which limits the content to less than or equal to the defined maxInclusive value. | maxInclusive value="12:00:00" allowed range .. - 12:00:00 |
| maxExclusive | Max Exclusive is the exclusive upper bound of the content component, which limits the content to less than the defined maxExclusive value. | maxExclusive value="12:00:00" allowed range ... - 11:59:59 |
| minInclusive | Min Inclusive is the inclusive lower bound of the content component, which limits the content to greater than or equal to the defined minInclusive value. | minInclusive value="12:00:00" allowed range 12:00:00 - .. |
| minExclusive | Min Exclusive is the exclusive lower bound of the content component, which limits the content to greater than the defined minExclusive value. | minExclusive value="12:00:00" allowed range 12:00:01 - .. |

Use
Time is used to reavailable a time on any day. Examples of times wake-up times each day or the time start and end time of a period of time such as the working day or lunch hour.
Notes
The reavailableation 24:00:00 (midnight) is not supported. Input and display of 24:00:00 could be possible in the context of an interval end time-point. Technically this is reavailableed as 00:00:00 the following day. The possibility to specify a time zone offset has been removed.
