## DateTimePicker
Select date and time in one picker.
:::tip
DateTimePicker is derived from DatePicker and TimePicker. For a more detailed explanation on `pickerOptions` and other attributes, you can refer to DatePicker and TimePicker.

### Date and time
:::demo You can select date and time in one picker at the same time by setting `type` to `datetime`. The way to use shortcuts is the same as Date Picker.
```html
Default
With shortcuts
```
:::
### Date and time range
:::demo You can select date and time range by setting `type` to `datetimerange`.
```html
Default
With shortcuts
```
:::
### Default time value for start date and end date
:::demo When picking date range on the date panel with type `datetimerange`, `00:00:00` will be used as the default time value for start and end date. We can control it with the `default-time` attribute. `default-time` accepts an array of up to two strings. The first item controls time value of the start date and the second item controls time value of the end date.
```html
Start date time 12:00:00
Start date time 12:00:00, end date time 08:00:00
```
