I've had my new to me U1 for three days now and have been loving it. That said, I recently noticed that it seemed fast - like 5 mins. fast!!!! I had re-set it when if got it on Xmas day.
I re-set it an hour ago and it has gained 7 secs in that hour. Clearly something is wrong.
Is someone able to provide some guidance on what I should do as I'm quite new to all this. I would really appreciate it.
