Strings encoded using Microsoft® JSON date-time format (for example, “/Date(1224043200000)/”) are always recognized as date-time values regardless of a value of this property. The property defines additional formats to be used while parsing date-time values from strings in the following way:
When ExactDateTimeParseFormats is null, the ISO-8601 format and all date-time formats supported for the current, English USA, and English New Zealand cultures are used additionally in the mentioned order.
When ExactDateTimeParseFormats contains strings, they are used as additional date-time formats utilizing the current culture.
When ExactDateTimeParseFormats is empty, no additional date-time formats are used.
