How do I update the Timezone on my Win7 clients simply by changing the timezone on the DC using GPO without using startup scripts.

Basically, I want to use GPO to update the clients whenever the timezone is updated on the DC. However, since most of my clients never log out of their PCs half the time, I want it done without having to reboot the machine or re-logon. I have already tried to pass the Time Zone Information registry from the DC to the client. It sucessfully updates the clients registry but doesn't actually change the time in the notofication area to reflect the time zone change. I mean, if you run regedit on the client, it shows the changed time zone. Yet, the clock is still on the time from the old time zone. What gives with that. Anyone have a better solution or can tell me what I am missing?

Since time by the system uses UTC time internally each computer can be in a different time zone only causing a visual display difference.

1. Method 1

On the server set the time zone to the desired time zone
Create a new gpo giving it a meaningful name expand Computer Configuration, Preferences, Windows Settings, Registry. Right-click Registry and select New
which will bring up the Registry Wizard  select Local. Navigate to \HKLM\System\CurrentControlSet\Control\TimeZoneInformation\  select all items and save the new gpo.

2. Method 2


On a good computer  export the \HKLM\System\CurrentControlSet\Control\TimeZoneInformation\ key as a .reg file and apply it to other clients using logon script via GPO

Your registry timezone change, does not update the actual time.

WMI/powershell/vb script run with or without psexec.
the script should check what the current time/tz are and then

you have to bring the clock after the timezone update close enough for the sync to work without causing authentication issues due to the time difference (clock + TZ adjustment).
