When a Smartphone is too smart for a Diabetic

Half way through my work tour of APAC and now in Sydney. I'm struggling to workout what timezone I'm in let alone what one I have come from and the time (and day!) back at home. Why does this matter? I take my long adding insulin Lantus around 10 pm every night. I'm already having enough fun trying to track my quick acting with new food, stress and heat, last thing I want is to be running empty on background.
