Correct Time

Hmmm... on wednesday, the clock went mad. It was 40 mins faster. Yesterday, when we woke up, we thought the clock was still wrong cos neither hubby nor I could be bothered to change it so we didn't get up. But when the alarm on my phone went off, I checked the time on my phone and compared it to the time on the clock.... It was the SAME!!! How weird is that?!?
