将其转换为Datetime，使用计算属性并按需格式化，参见MM/dd/yyyy的示例，查看更多信息，请参阅此链接。

$xml.rss.channel | % {$_.item} | 
select @{N="pubdate";E={([datetime]$_.pubdate).ToString("MM/dd/yyyy")}},title

$xml.rss.channel | % {$_.item} | 
select @{N="pubdate";E={([datetime]$_.pubdate).ToString("MM/dd/yyyy")}},title

$url = "http://feeds.marketwatch.com/marketwatch/marketpulse"
[xml]$xml = (new-object System.Net.WebClient).DownloadString($url)
$xml.rss.channel | Foreach {$.item} | select @{N="pubdate";E={[System.TimeZoneInfo]::ConvertTimeBySystemTimeZoneId([datetime]$.pubdate, 'Eastern Standard Time').ToString("ddd MMM d HH:mm:ss")}},title

不需要转换。只需确保您从XML中将日期作为字符串读取，然后将其转换为DateTime。请尝试以下代码：

```powershell
using assembly System.Xml.Linq

$uri = 'http://feeds.marketwatch.com/marketwatch/marketpulse'
$doc = [System.Xml.Linq.XDocument]::Load($uri)
$items = $doc.Descendants('item')

$table = [System.Collections.ArrayList]@()

foreach ($item in $items) {
    $title = $item.Element('title').Value
    $link = $item.Element('link').Value
    $description = $item.Element('description').Value
    $pubDate = [DateTime]$item.Element('pubDate').Value
    $guid = $item.Element('guid').Value

    $newRow = [psobject]@{
        'Title' = $title
        'Link' = $link
        'Description' = $description
        'Pub Date' = $pubDate
        'guid' = $guid
    }
    $table.Add($newRow) | Out-Null
}
$table | Format-Table

这段代码的作用是从指定的XML源加载数据，并将日期字段转换为DateTime类型，然后将结果以表格格式输出。

using assembly System.Xml.Linq

$uri = 'http://feeds.marketwatch.com/marketwatch/marketpulse'
$doc = [System.Xml.Linq.XDocument]::Load($uri)
$items = $doc.Descendants("item")

$table =  [System.Collections.ArrayList]@()

foreach($item in $items)
{
   $title = $item.Element('title').Value
   $link = $item.Element('link').Value
   $description = $item.Element('description').Value
   $pubDate = [DateTime]$item.Element('pubDate').Value
   $guid = $item.Element('guid').Value

   $newRow = [psobject]@{
      'Title'=$Title
      'Link'=$link
      'Description'=$description
      'Pub Date'=$pubDate
      'guid'=$guid
   }
   $table.Add($newRow) | out-null
}
$table | Format-Table
