I know this is an old request, but I'd like to +1 it. When you change timezones, the additional clock for other timezones feature is really great. In fact, having the date and time at all on my secondary displays is one of the reasons for me to still use DisplayFusion on Win10. When I can just mouseover the time and see other time zones, it keeps me from making a mental mistake or adding hours instead of subtracting, etc. Would love to see this!
