/**
* A composite field for date and time entry,
* based on {@link DateField} and {@link TimeField}.
* Usually saves into a single {@link DBDateTime} database column.
* If you want to save into {@link Date} or {@link Time} columns,
* please instanciate the fields separately.
*
* This field does not implement the <input type="datetime-local"> HTML5 field,
* but can use date and time HTML5 inputs separately (through {@link DateField->setHTML5()}
* and {@link TimeField->setHTML5()}.
* Form field used for editing date time string
*
* # Configuration
*
* Individual options are configured either on the DatetimeField, or on individual
* sub-fields accessed via getDateField() or getTimeField()
*
* Example:
* <code>
* $field = new DatetimeField('Name', 'Label');
* $field->getDateField()->setTitle('Select Date');
* </code>
*
* - setLocale(): Sets a custom locale for date / time formatting.
* - setTimezone(): Set a different timezone for viewing. {@link dataValue()} will still save
* - "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.
* - setDateTimeOrder(): An sprintf() template to determine in which order the date and time values will
* - "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.
