Florian Müllner 60f6715228 util: Use GLib.DateTime in formatTime()
The world clock uses GLib.DateTime instead of the built-in Date type
because of the much superior timezone support, and therefore cannot
use the new formatTime() helper. To make this possible, modify the
method to support a parameter of either type.
