Represents an extent in time bounded by begin and end dateTimes. If <begin> or <end> is missing, then that end of the period is unbounded (see Example below). The dateTime is defined according to XML Schema time (see XML Schema Part 2: Datatypes Second Edition). The value can be expressed as yyyy-mm-ddThh:mm:ss.ssszzzzzz, where T is the separator between the date and the time, and the time zone is either Z (for UTC) or zzzzzz, which represents ±hh:mm in relation to UTC. Additionally, the value can be expressed as a date only. See <TimeStamp> for examples.
