Set Regional Settings for Sharepoint 2010 Sites

Somebody at work forgot to change the regional settings to UK and since we have quite a few sites on our Sharepoint installation, I thought it would be a good idea to script the procedure rather than do it manually, so here it is:

The script takes a single parameter, which is the SharePoint base Url and sets all sites within to UK regional settings, change the GetCultureInfo line to your Locale.

 param ($url) 

 $snapin ="Microsoft.sharepoint.powershell" 

 if (-not $url) 
 { 
 write-host "Please Invoke script like this:  SetRegionalSettings.ps1 -url `"http://sp.dev.com/`"" 
 exit 
 } 

 if ( (Get-PSSnapin -Name $snapin -ErrorAction SilentlyContinue) -eq $null ) 
 {     
  Add-PSSnapin $snapin -ErrorAction SilentlyContinue 
 } 
 
 try 
 { 
  $sites = Get-SPweb -site $url -limit all 
 } 
 catch 
 { 
  Write-Error "An error occurred while retrieving the sharepoint sites for $url" 
 } 
 if ($sites -ne $null) 
 { 
  foreach ($site in $sites) 
  { 
   try 
    { 
     $site.Locale = [System.Globalization.CultureInfo]::GetCultureInfo("en-GB");    
     Write-Host "Changing Regional Settings for Site $($site.Name) to $($site.Locale.DisplayName)"   
     $site.Update() 
    } 
    catch  
    { 
     Write-Error "An error occurred while changing regional settings" 
    } 
  } 
 }
