###  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
<template>
  <div class="block">
    <span class="demonstration">Default</span>
    <el-date-picker
      v-model="value1"
      type="datetime"
      placeholder="Select date and time">
    </el-date-picker>
  </div>
  <div class="block">
    <span class="demonstration">With shortcuts</span>
    <el-date-picker
      v-model="value2"
      type="datetime"
      placeholder="Select date and time"
      :shortcuts="shortcuts">
    </el-date-picker>
  </div>
  <div class="block">
    <span class="demonstration">With default time</span>
    <el-date-picker
      v-model="value3"
      type="datetime"
      placeholder="Select date and time"
      :default-time="defaultTime">
    </el-date-picker>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        shortcuts: [{
          text: 'Today',
          value: new Date(),
        }, {
          text: 'Yesterday',
          value: (() => {
            const date = new Date();
            date.setTime(date.getTime() - 3600 * 1000 * 24);
            return date
          })(),
        }, {
          text: 'A week ago',
          value: (() => {
            const date = new Date();
            date.setTime(date.getTime() - 3600 * 1000 * 24 * 7);
            return date
          })(),
        }],
        value1: '',
        value2: '',
        value3: '',
        defaultTime: new Date(2000, 1, 1, 12, 0, 0) // '12:00:00'
      };
    }
  };
</script>

<setup>

  export default defineComponent({
    setup() {
      const state = reactive({
        shortcuts: [
          {
            text: 'Today',
            value: new Date(),
          },
          {
            text: 'Yesterday',
            value: (() => {
              const date = new Date();
              date.setTime(date.getTime() - 3600 * 1000 * 24);
              return date;
            })(),
          },
          {
            text: 'A week ago',
            value: (() => {
              const date = new Date();
              date.setTime(date.getTime() - 3600 * 1000 * 24 * 7);
              return date;
            })(),
          },
        ],
        value1: '',
        value2: '',
        value3: '',
        defaultTime: new Date(2000, 1, 1, 12, 0, 0), // '12:00:00'
      });

      return {
        ...toRefs(state),
      };
    },
  });

</setup>

### Date and time range

:::demo You can select date and time range by setting `type` to `datetimerange`.

###  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 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"
      align="right"
      start-placeholder="Start Date"
      end-placeholder="End Date"
      :default-time="defaultTime2">
    </el-date-picker>
  </div>

  export default {
    data() {
      return {

        defaultTime1: [
          new Date(2000, 1, 1, 12, 0, 0),
        ], // '12:00:00'
        defaultTime2: [
          new Date(2000, 1, 1, 12, 0, 0),
          new Date(2000, 2, 1, 8, 0, 0)
        ] // '12:00:00', '08:00:00'
