* Multi-DateTime property
|
|

|
|
* This element is used for iCalendar properties such as the EXDATE property.
|
|
* It basically provides a few helper functions that make it easier to deal
|
|
* with these. It supports both DATE-TIME and DATE values.
|
|
*
|
|
* In order to use this correctly, you must call setDateTimes and getDateTimes
|
|
* to retrieve and modify dates respectively.
|
|
*
|
|
* If you use the 'value' or properties directly, this object does not keep
|
|
* reference and results might appear incorrectly.
