* Declares that a field should be formatted as a date time.
* Supports formatting by style pattern or by format pattern string.
* Supports formatting by style pattern, custom format pattern string, or ISO date time pattern.
* Can be applied to <code>java.util.Date</code>, <code>java.util.Calendar</code>, <code>java.long.Long</code>, or Joda Time fields.
* <p>
* For style-based formatting, set the <code>style</code> attribute to be the style pattern.
* The first character is the date style, and the second character is the time style.
* For style-based formatting, set the {@link #style()} attribute to be the style pattern code.
* The first character of the code is the date style, and the second character is the time style.
* Specify a character of 'S' for short style, 'M' for medium, 'L' for long, and 'F' for full.
* A date or time may be omitted by specifying the style character '-'.
* <p>
* For pattern-based formatting, set the <code>pattern</code> attribute to be the DateTime pattern, such as <code>yyyy/mm/dd h:mm:ss a</code>.
* If the pattern attribute is specified, it takes precedence over the style attribute.
* For pattern-based formatting, set the {@link #pattern()} attribute to be the DateTime pattern, such as <code>yyyy/mm/dd h:mm:ss a</code>.
* <p>
* If no annotation attributes are specified, the default format applied is style-based with a style code of 'SS' (short date, short time).
* For ISO-based formatting, set the {@link #iso()} attribute to be the desired {@link ISO} format, such as {@link ISO#DATE}.
* <p>
* Each attribute is mutually exclusive, so only set one attribute per annotation instance (the one most convenient one for your formatting needs).
* When the pattern attribute is specified, it takes precedence over both the style and ISO attribute.
* When the iso attribute is specified, if takes precedence over the style attribute.
* When no annotation attributes are specified, the default format applied is style-based with a style code of 'SS' (short date, short time).
