I have a question to see if at least it's possible. I would like a clock (for example Presto's clock that I've been using and like) that if you use the scroll wheel of the mouse on top of the clock, it changes depending on the (already) set time zones (through settings). To be even more specific, I wonder if there is the possibility to have multiple clocks depending on time zones but within the same instance of the widget through which you can scroll.
Without the need to open multiple instances and occupying too much space of the desktop. I know the Win 7 built in clock has the possibility to show up to 3 clocks but that's not enough unfortunately.
Just in case somebody didn't get the idea here's an example:
clocks shows Los Angeles time, you scroll down with the scroll wheel of the mouse, now the clock shows Melbourne time, you scroll down again with the scroll wheel, now the clock shows Paris time and so forth.
