The formatted string can be parsed back by using the DateTime.Parse(String, IFormatProvider, DateTimeStyles) or DateTime.ParseExact method if the styles parameter is set to DateTimeStyles.RoundtripKind. These settings are used to initialize the DateTimeFormatInfo object associated with the current thread culture, which provides values used to govern formatting. If a particular format specifier produces a localized result string, the example also notes the culture to which the result string applies. Four standard format strings fall into this category: "O" (or "o"), "R" (or "r"), "s", and "u". If non-zero, the millionths of a second in a date and time value.
