Timezone set via subnet / branch office with no DC

We need to set timezone for our sites based on subnet, as we do not have any domain controllers at each site.  All sites are connected via an MPLS.

We have users moving before tmezones and need to auto update there devices with the local timezone when they connect.

Any assistance would be greatly appreciated

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can set the timezone through a Group Policy with either a powershell script (http://blogs.technet.com/deploymentguys/archive/2009/06/07/setting-the-time-zone-using-windows-powershell.aspx) or Registry settings.

Make sure you have different Sites (Active Directory sites and services) with the correct IP subnets linked to these sites.  

You can apply this group policy to this site.  Right now users who login to the domain on a different site will get the correct timezone.

Best regards
