1つのピッカーで日時を選択します。

:::tip
DateTimePickerはDatePickerとTimePickerから派生したものです。属性についての詳しい説明は、DatePickerとTimePickerを参照してください。

###  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。

```html
<template>
  <div class="block">
    <span class="demonstration">Default</span>
    <el-date-picker

###  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>
    <el-date-picker
      v-model="value1"
      type="datetimerange"
      start-placeholder="Start Date"
      end-placeholder="End Date"
      :default-time="defaultTime1">
    </el-date-picker>
  </div>
  <div class="block">
    <span class="demonstration">Start date time 12:00:00, end date time 08:00:00</span>
    <el-date-picker
      v-model="value2"
      type="datetimerange"
      start-placeholder="Start Date"
      end-placeholder="End Date"
      :default-time="defaultTime2">
    </el-date-picker>
