Determining Client's Time Zone

[Guest]

I am attempting to solve a date/time formatting issue is
VBScript ASP pages. The ASP pages needs to determine what
time zone the client browser is in and tell a COM object.
The COM object then reads information from a proprietary
file and formats the date/time into the appropriate time
zone and returns the information to the ASP in an XML
form.

My question is how do I determine the client's time Zone
using VBScript in ASP pages?

Thanks,
Mike
