Where can I find a class written in c++ that will allow me to give it a time zone/time to convert to UTC?

All I have been able to find are classes that look at the time zone information stored on the local computer. I need to be able to supply a time zone for the conversion.

Where can I find a class written in c++ that will allow me to give it a time zone/time to convert to UTC?
