Added a local time feature

I added a local time feature so our family and friends will understand why we call them so early in the morning. Ghana is 5 hours ahead of us and I selected the 24 hour clock common to the military and also most European countries. I'm not sure what they use in Ghana but most train/bus schedules in the countries I've traveled to use the 24 hour clock. Anyway, for me, it's fun to tell time in this fashion.
