Remember In the good old Windows XP days, when the Time Zone you used when creating your Sysprep.inf/Unattend.txt was just a number you could look up in a Microsoft table (and properly also remember)

Well those days are almost gone and now you will have to use Time Zone ID which is a Name rather than a number, so the Danish time zone that used to be 105, is now Romance Standard Time

So the question then is, where do i get a hold of those names?? The answer is simple…TZUTIL which is an embedded windows 7 command line tool.

Just run TZUTIL /l from a prompt in Win7 and you will get at a full list
