You can determine the timezone using javascript (as an integer): var visitortime = new Date(); visitortime.getTimezoneOffset()/60; You can then set this value either in a cookie or in a hidden form field, depending on whether you would like to reverify the timezone on every page or just when registering. You'll have to map this number to an appropriate timezone (make an educated guess). Do know that javascript will give you the opposite of what you will expect: Brussels for example will give -2 as a result while it is GMT+2.
