What's that time Zone....

A few weeks ago I was asked to image a couple of laptops by a global company. The laptops had been previously deployed at 2 of there overseas sites. After imaging the drives I went to look at the bios for the machines so I could document the settings and the date/time. After looking at the date/time I wondered what time zone it was. Now since I am lazy and really only want to do this once I came up with this little autoit gui program that will tell me what time zone a specific date/time is from compared to my time zone.

For example if the my current date/time is 10/30/2007 8:30:00 and the bios date/time setting 10/30/2007 19:00:00 then the time zone setting is GMT+5:30. Possible areas that may be in this time zone are Chennai, Kolkata, Mumbai, New Delhi, Sri Jayawardenepura.

The program can be found here. Once you start up the program it will put the current date/time in the 2 fields, You will have to make the change to the date/time to figure out field then click on the "get time zone information". It will then bring up a box with the potential cities for that time zone (based on windows time zones).
