|
|
* A String whose value is a valid representation of a Date.
|
|
* Use this type if you need to preserve the format of the value and still
|
|
* check if it's valid.
|
|
* Example:
|
|
* ```js
|
|
* var loopback = require('loopback');
|
|
* var dt = new loopback.DateString('2001-01-01');
|
|
*
|
|
* dt.toString();
|
|
* // '2001-01-01'
|
|
* dt._date.toISOString();
|
|
* // '2001-01-01T00:00:00.000Z'
|
|
* ```
