I work with people from multiple timezones and I loved how I could have several displayed under my main time in gnome2 (I was using scientific linux). I happen to have a screenshot of it as you can see below.

However on Fedora 22 (KDE 5.12) the timezone panel sucks. It doesn't even show when one time is for a different date.

How could I go about getting something like the first picture on KDE? Or at least something better than what is there now.
