Nullable<int>
Data types with a question mark - an example is [int?] but this can apply to any data type - are defined as null. Most data types are not nullable in this API framework, so this data type allows you to accept null for a non-nullable type. By default, nullable types are strings.
TimeSpan

- 00:00 - 23:59 (hours and minutes)

- 00:00:00.000 - 23:59:59.999 (hours, minutes, seconds, and milliseconds)
- 1.00:00:00 - 99999.23:59:59 (date, hours, minutes, seconds)
- 1.00:00:00.000 - 99999.23:59:59.999 (date, hours, minutes, seconds, and milliseconds)
