The Grandfather Clock takes it's time directly from the system time on your computer. If it is displaying the wrong time (or speaking the wrong time) check your system clock to make sure it is set correctly. If it speaks "AM" during the PM and "PM" during the AM it sounds like your system clock might be 12 hours off.
My Mom went and bought a big Grandfather clock at Wal-Mart, can't get the stupid thing to chime. I loaded your widget and set my laptop on her Kitchen table, she loves it. I have it to chime between 8am and 10pm.
Good Job !!!!!!!!!!!!!!
