/**
|
|
* A composite field for date and time entry,
|
|
* based on {@link DateField} and {@link TimeField}.
|
|
* Usually saves into a single {@link SS_Datetime} database column.
|
|
* If you want to save into {@link Date} or {@link Time} columns,
|
|
* please instanciate the fields separately.
|
|
*
|
|
* # Configuration
|
|
*
|
|
* The {@link setConfig()} method is only used to configure common properties of this field.
|
|
* To configure the {@link DateField} and {@link TimeField} instances contained within, use their own {@link setConfig()} methods.
|
|
*
|
|
* Example:
|
|
* <code>
|
|
* $field = new DatetimeField('Name', 'Label');
|
|
* $field->setConfig('datavalueformat', 'YYYY-MM-dd HH:mm'); // global setting
|
|
* $field->getDateField()->setConfig('showcalendar', 1); // field-specific setting
|
|
* </code>
|
|
*
|
|
* - "timezone": Set a different timezone for viewing. {@link dataValue()} will still save
|
|
* the time in PHP's default timezone (date_default_timezone_get()), its only a view setting.
|
|
* Note that the sub-fields ({@link getDateField()} and {@link getTimeField()})
|
|
* are not timezone aware, and will have their values set in local time, rather than server time.
|
|
* - "datetimeorder": An sprintf() template to determine in which order the date and time values will
|
|
* be combined. This is necessary as those separate formats are set in their invididual fields.
|
|
