Interesting thought about the UK time, but I'm not sure that the H9 itself cares – it does not have a real-time clock. I am concerned that it may be some kind of computer issue that will be hard for us to reproduce.
My guess is that unless you can resolve it at your end, you are going to send it to us to look at it. If you decide to do so, contact firstname.lastname@example.org first.
