Date, Time and Duration Datatype Summary

Takeaways:

XSD 1.1 supports 12 date, time and duration related built-in datatypes: "dateTime", "dateTimeStamp", "date", "time", "gYear", "gMonth", "gDay", "gYearMonth", "gMonthDay", "duration", "yearMonthduration" and "dayTimeduration".
They are defined using data models similar to "ISO 8601 - Data elements and interchange formats" standard.
Date and time related built-in datatypes uses a 7-property model: "year", "month", "day", "hour", "minute", "second" and "timezoneOffset"
"dateTime" datatype support all 7 date and time properties using this pattern: /(year)-(month)-(day)T(hour):(minute):(second)(timezoneOffset)?/.
Duration related built-in datatypes uses a different 7-property model: "duSign", "duYear", "duMonth", "duDay", "duHour", "duMinute" and "duSecond".
"duration" datatype support all 7 duration properties using this pattern: /(duSign)P(duYear)?(duMonth)?(duDay)?(T(duHour)?(duMinute)?(duSecond)?)?/.
