Powershell重新启动控制台问题

Question

我有一个登录脚本，如果PC的运行时间超过允许的时间，它会重新启动PC。

我有一个 PowerShell 脚本，该脚本在登录期间运行并每周执行一次，以检查计算机正常运行时间并在 48 小时内>重新启动。该脚本允许用户请求扩展，这样他们就不会立即被踢出计算机。我有 1、3、8 小时的延期。只有1,3小时的延长工作。似乎如果您输入大于 3 的值，它不接受它。 有没有办法让这个"扩展"工作超过 3 小时？

我想允许 8 小时延期，但它不允许> 3 小时。

这是

可执行文件shutdown.exe的限制。根据此处找到的文档：

https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/shutdown

/t <XXX>    Sets the time-out period or delay to XXX seconds before a restart or 
            shutdown. This causes a warning to display on the local console. You can 
            specify 0-600 seconds. If you do not use /t, the time-out period is 30 
            seconds by default.

如果要超越此范围，则必须在执行shutdown.exe之前在PowerShell中创建暂停。这可以通过在 8 小时选项中添加start-sleep，睡眠 3 小时，然后指定最大 600 秒计时器来完成。

编辑：看起来该文档已过时，并且关闭现在接受长达 10 年的任何内容(以秒为单位格式化(。看，关机命令只需要几秒钟。你应该能够用秒 x 分钟 x 小时来计算它，而不是你正在尝试的所有花哨的数学。一分钟 60 秒，一小时 60 分钟，所以唯一改变的是延迟的小时数。试试这个：

$Global:hash.ScheduleBtn.Add_Click( {
    $startTime = switch ($Global:hash.ScheduleValue.SelectedItem.Name) { 
        "one" { 1*60*60 } 
        "three" { 3*60*60 } 
        "eight" { 8*60*60}
    }
    $Global:hash.Timer.Stop()
    cmd.exe /c shutdown.exe -r -d P:0:0 -t $startTime -f 
    $Global:hash.Window.Close()
}
