I often move between 2 time zones, and expect my Windows 7 laptop to somehow automatically change the system time, being spoiled by the same feature on my cell phone. I always assumed that desktop O/Ses simply did not do this, but I was shocked yesterday when I noticed that OSX on the MacBook actually does this!

Does anybody know of any utilities that does this on Windows, specifically Windows 7? There has to be something out there?

you will have to get a soft for this as don't know another way to get this to work in windows (as configuring NTP will not be affected with time zone changes) and you may try Atomic Clock Sync.

Thanks. Looked at atomic clock sync and it doesn't seem to do what I had in mind. Any other ideas? – Suan May 22 '11 at 1:39

Seems like there just isn't any software that provides this functionality for Windows.

If you're on a corporate network, this will have even more problems. Unless the system has a built-in GPS chip by which it can get it's location and precise timezone, it will determine it's location by it's public IP and IP-geolocation. On a corporate network this will always be determined by the domain controller, which is generally in a static location geographically.

If your system is not on a domain, relying on the public IP and geolocation will still be problematic if you're near a time zone boundary, as you never know if your IP is being handed out by a server across the line.

It may be easiest to write a bit of code that runs in the system tray and allows you to simply select the appropriate time zone and then updates your system clock accordingly.

Microsoft has a Time Zone tool that allows you to set and display multiple time zones. I have not checked to see how easy it is to switch between favorites as your current zone, but it may be a step in the right direction.

There isn't a simple, easy way to have this done automatically. However, you could add a 2nd clock, and see them both at the same.

I'm not at my PC now, I'll explain how later. – wizlog May 24 '11 at 14:35
