What day is it today?

After dinner and a little chilling out with sis and few friends, I was once again brought myself into this beautiful in blue room. This is my last night home. It's time to go back to reality after the smiley dream has almost came to an end. I turned the small and old in age radio on. I picked my bag, searching for my phone. I had it recharged. My brain thought of my tomorrow departure. I need to check the time. It's the usual time, however, I have to see the time once again for confirmation. Feeling lazy, I, instead, came online, checked mail,... August 28 What??? Today is 27, isn't it??? I mean, how could this be??? I checked my phone, it said August 28. How could this ever happened??? I suddenly went out to talk to my mum. She was already asleep. I came back. I went out of my room to search for people. I found 3. I asked them, "what day is it today?". One of them said, "It's 27". "Are you confused?", she asked. I didn't answer. I just went back here to confirm my doubt. Technology is not perfect. This PC was set to Australia time. It was once there. I thought I had it changed, but I didn't. Now that I did it, today is August 27, 10:57PM.
