Display Time

Hi,

I’m working on an aquaponics system and I’m trying to make it as automated as I can. So far I have installed a relay (to turn on a pump every 30 minutes), a pH sensor and an lcd shield that will display the pH value of my fish tank. What I want to do next is have my LCD display the time my pump toggled on or off. Right now it’s trying to display the complete date (ex. July 21, 2015 12:23:34) and I only want it to display the time, not the date. I have attached the code I am using. Are the any suggestions as to what I need to do to get display the time?

I also forgot to mention that I am using a DS3234 RTC.
