Reset the clock. Seems to work fine now.
Okay, the clock was running exactly 12 hours and 10 minutes ahead, and could not get it to reset using the app(Mac). I decided to do this: I removed the on board battery to completely clear the timer/clock, and then replaced battery at exactly midnight with the hopes to get correct time. The clock started at zero, but within three minutes the clock had already jumped ahead by seven minutes. Huh? I attached to my computer, a MacBook Pro, fired up the app, clicked all the buttons(port, start, save, etc.), and amazingly, it now has correct local time. Disconnected and plugged into a 5 volt USB adapter, and so far, it seems to be working perfectly. Maybe this info might help someone else. Good luck.
