如何自动获取时区详情及夏令时信息？PowerShell脚本报错求助

错误原因 #

报错源于Write-Host "Time zone details for $server:"这行代码：PowerShell会将$server:识别为驱动器引用语法（如C:、HKCU:），而非变量$server后追加冒号，导致变量解析失败。

修复方案 #

方案1：用${}明确变量边界 #

通过${server}包裹变量名，让PowerShell准确识别变量范围：

$servers = "server1", "server2", "server3" # 替换为目标服务器名称

foreach ($server in $servers) {
    Write-Host "Time zone details for ${server}:"
    $timezone = Get-WmiObject -Class Win32_TimeZone -ComputerName $server
    $timezone | Select-Object Caption, StandardName, DaylightName, Bias
    Write-Host ""
}

方案2：使用格式化字符串 #

通过-f格式化运算符拼接字符串，避免变量与特殊字符冲突：

$servers = "server1", "server2", "server3" # 替换为目标服务器名称

foreach ($server in $servers) {
    Write-Host ("Time zone details for {0}:" -f $server)
    $timezone = Get-WmiObject -Class Win32_TimeZone -ComputerName $server
    $timezone | Select-Object Caption, StandardName, DaylightName, Bias
    Write-Host ""
}

推荐优化（可选） #

在PowerShell 5.1及以上版本，推荐用Get-CimInstance替代已被弃用的Get-WmiObject，兼容性和性能更好：

$servers = "server1", "server2", "server3" # 替换为目标服务器名称

foreach ($server in $servers) {
    Write-Host "Time zone details for ${server}:"
    $timezone = Get-CimInstance -Class Win32_TimeZone -ComputerName $server
    $timezone | Select-Object Caption, StandardName, DaylightName, Bias
    Write-Host ""
}
