How to change time format in the front end?

Hello guys,
I would like to change the time format for the front end to show 9:00 AM as the Start time and 9:00 PM as the end time on the Booking Hours. I was trying to figure it out making changes to the configurations. After some tries the cart is showing the correct format for the time, but the booking times still show 09:00 and 21:00. Is there a workaround for this?
Thanks in advance.

Just one quick question:
Why if it is still 12/14/2012 my active day is tomorrow. I have set the timezone to GMT-5 since we have EST time one. What am I doing wrong?
