### 日付と時間

:::demo `type`を`datetime`に設定することで、1 つのピッカーで日付と時刻を同時に選択することができます。ショートカットの使い方は日付ピッカーと同じです。

### 開始日と終了日のデフォルトの時間値

:::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 Date objects. The first item controls time value of the start date and the second item controls time value of the end date.

```html
<template>
  <div class="block">
    <span class="demonstration">Start date time 12:00:00</span>
