for those of you that have them, which world clock software do you use on the desktop (Windows)? I need an easy lookup of a time in a certain place type program so that I don't call someone at 3am in the morning

also, I'm looking for the world time clock v1.1 plugin for trillian if anyone know where I can download it, that would be great. Please do not say the trillian site as the link there is dead.
