Update All Web Applications with Powershell

long time no post

just a quick post with a simple command. I needed to update all the Default Time zone settings for all the web applications in a SharePoint 2010 farm.

Here’s how to do it in a single command:
Get-SPWebApplication |Foreach-Object { $_.DefaultTimeZone = 3 ; $_.Update() }

The value 3 stands for the time zone (UTC +01:00) Brussels, Copenhagen, Madrid, Paris
