26 Jun Get and Set Timezones via PowerShell
As published in my Technet Gallery Script Center here, you can get current timezones remotely via PowerShell with Get-Timezones. Get-Timezones is using WMI to communicate with your servers.
Function Get-Timezones { <# .SYNOPSIS Retrieves timezones of local or remote computers via WMI. .DESCRIPTION Retrieves timezones of local or remote computers via WMI. .PARAMETER ComputerName A single Computer or an array of computer names. The default is localhost ($env:COMPUTERNAME). .PARAMETER Credentials Commit Credentials for a different domain. .PARAMETER Verbose Run in Verbose Mode. .EXAMPLE PS C:\&amp;amp;gt; Get-Timezones -ComputerName (gc 'C:\computers.txt') -Credentials Get-Credential ComputerName TimezoneName DaylightSaving TimezoneCaption ------------ ------------ -------------- --------------- SERVER01 W. Europe Standard Time yes (UTC+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna SERVER02 W. Europe Standard Time yes (UTC+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna .NOTES Author: Sebastian Gräf Website: https://graef.io Email: ps@graef.io Date: June 27, 2017 PSVer: 3.0/4.0/5.0 #> [Cmdletbinding()] Param ( [Parameter(ValueFromPipelineByPropertyName = $true, ValueFromPipeline = $true)] $ComputerName = $Env:COMPUTERNAME, [Parameter(ValueFromPipelineByPropertyName = $true, ValueFromPipeline = $true)] [ValidateNotNull()] [System.Management.Automation.PSCredential][System.Management.Automation.Credential()] $Credentials = [System.Management.Automation.PSCredential]::Empty ) Begin { Write-Verbose " [$($MyInvocation.InvocationName)] :: Start Process" $Results=@() $ProgressCounter = 0 } Process { foreach ($Computer in $ComputerName) { $ProgressCounter++ Write-Progress -activity "Running on $Computer" -status "Please wait ..." -PercentComplete (($ProgressCounter / $ComputerName.length) * 100) if (Test-Connection $Computer -Count 1 -Quiet) { Write-Verbose " [$($MyInvocation.InvocationName)] :: Processing $Computer" try { $win32_timezone = Get-WmiObject -Class win32_timezone -ComputerName $Computer -ErrorAction Stop -Credential $Credentials if ($win32_timezone.DaylightBias -eq 0) { $daylightsaving = "no" } else { $daylightsaving = "yes" } $obj = New-Object -Type PSCustomObject -Property @{ ComputerName = $Computer TimezoneCaption = $win32_timezone.Caption TimezoneName = $win32_timezone.StandardName DaylightSaving = $daylightsaving } $Results += $obj } catch { Write-Verbose " Host [$Computer] Failed with Error: $($Error[0])" } } else { Write-Verbose " Host [$Computer] Failed Connectivity Test" } } $Results | select ComputerName,TimezoneName,DaylightSaving,TimezoneCaption } End { Write-Progress -activity "Running on $Computer" -Status "Completed." -Completed Write-Verbose " [$($MyInvocation.InvocationName)] :: End Process" } }This will give you following output:
With Set-Timezone you can set timezones remotely. If you need to disable automatic daylight saving time you can add the additional parameter DSTOff.
Function Set-Timezones { <# .SYNOPSIS Sets and retries timezones on local or remote computers via WinRM and enables or disables daylight saving. .DESCRIPTION This PowerShell function sets and retrieves the timezone of a local or remote computer using WinRM (Invoke-Command). It also enables or disables dayligt saving times. The function accepts pipeline input and outputs to the pipeline as well as credentials if you want to run it for a specific domain. If the remote computer won't be accessible the function will catch the error but will continue to work. You can use tzutil /l to get a list of available time zone IDs. Timezone TimeZoneID --------- ---------- (UTC-06:00) Central Time (US &amp;amp;amp; Canada) Central Standard Time (UTC) Coordinated Universal Time UTC (UTC+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna W. Europe Standard Time .PARAMETER TimezoneID A single Computer or an array of computer names. The default is localhost ($env:COMPUTERNAME). .PARAMETER DSTOff Enables or disables Daylight Saving Time adjustments for the time zone (where applicable). Default: ON If switch parameter DST committed as true, Daylight saving Time will be disabled. .PARAMETER ComputerName A single Computer or an array of computer names. The default is localhost ($env:COMPUTERNAME). .PARAMETER Credentials Commit Credentials for a different domain. .PARAMETER Verbose Run in Verbose Mode. .EXAMPLE PS C:\&amp;amp;gt; Set-Timezones -ComputerName (gc 'C:\computers.txt') -TimezoneID "W.
