Taking time zones into account when planning a trip

[Ron Gardiner]

I have been using the Web Routeplanner for sometime and like all the features, I'm looking for a way that I can have it adjust for timezones. I live in EST (Canada) and travel out west passing thru several timezones on my trip. One of the features I like is that if I tell it what time I leave it tells me the time I arrive at my destination (even taking into account all my stops on the way), together with the travel time and distance. I have seen other planners that take the timezone into account when showing your arrival time. Any way that could be added here as a feature?
