/**
|
|
* Represents a date-time field.
|
|
* The field currently supports New Zealand date format (DD/MM/YYYY),
|
|
* or an ISO 8601 formatted date and time (Y-m-d H:i:s).
|
|
* Alternatively you can set a timestamp that is evaluated through
|
|
* PHP's built-in date() and strtotime() function according to your system locale.
|
|
*
|
|
* For all computations involving the current date and time,
|
|
* please use {@link SS_Datetime::now()} instead of PHP's built-in date() and time()
|
|
* methods. This ensures that all time-based computations are testable with mock dates
|
|
* through {@link SS_Datetime::set_mock_now()}.
|
|
*
|
|
* @todo Add localization support, see http://open.silverstripe.com/ticket/2931
