Timezones in clock

[Viktor Semykin]

Hello everyone.

I've implemented a nice widget showing world map with timezone points on 
it and integrated the widget in clock panel plugin. You can find my code 
here [1].

The question is, could this feature be possibly integrated to the panel 
code when its quality gets good enough for it?

There are couple of questions I want to discuss too:

1. I found at least three implemetations of timezones in xfce itself and 
glib: [2], [3], [4]. And in addition to them I had to create my own 
implementation in [1]. Maybe we have a reason to implement featureful 
time zone support in libxfce4util?

2. Timezone selection widget can be useful in other places except clock 
plugin. Should it be moved to libxfce4ui?

-- 
best, Viktor.
